Punchy In the good old days, when men were men and you could log in as root, /sbin wasn't needed. You can still log in as root on Ubuntu/Kubuntu/Xubuntu/Lubuntu/Mint/Etc... You just need to set a root password first. sudo su <Enter your normal user password> passwd <enter a root password> And then you can log in as root, just as if it were any other user account.

None of the commands so far seem to work to make it drop to the pure terminal mode. But I did find something interesting by logging out. In this Mint version there are option for different ways to login to the GUI. Some without all the extra fancy stuff such as Cinnamon witch was using some of the CPU cycles ever so often. Now to see how many seconds this way may help. The sudo su did work and was able to enter root, setup a password, but still unable to drop to just straight terminal mode. Still some great help here, I'm learning. Thanks guys!

A good read and informative for me. Thanks Wolf for that news-bit on being able to set the File type on Mint14. I'd always wondered (ala Punchy's comment/test) if running the GUI had any significant detrimental impact. Good to hear that I can just run the GUI 'cause I like it a lot better than text mode. Wolf, just do what I do and use another PC when the mood hits to want to do some browsing. Actually, I just grab the Tablet and it serves that purpose very well. Yep, you hafta leave those Bigadv rigs alone to get the best out of them and especially so with a 2P where deadlines can be close.

Setting the File Type to EXT3 is still in testing. Its actually looking pretty good on frame times for the CPU speed 3.0 and 24 cores at 29:15 avg. CPU-G "a Linux CPU-Z" only shows it running at 2.934 but I think it actually running 3.0/3.1Ghz with the turbo on. Found a few cool little programs for checking things out such as CPU-G & Psensor. Both pretty easy to install and setup. Ya I'll be leaving it alone more now that I have about everything setup the way I like it. Still might try a few more tweaks.

i7z from Google Code is the most reliable way I know of to check the actual speed on Intel processors. I have not tried CPU-G so I can't compare.

Xavier Zepherious linux mint 14? well I guess I'll have to install that on the new rig (when I get that running) How do you like linux mint? I actually like it very much. Wasn't to hard to get use to. Found you can go to home\fah folder and from there open a terminal by right clicking and picking terminal from the popup menu so you can skip the CD fah in a normal terminal. But where this comes in handy "for me" is when setting up different packages I download "some with crazy names" I can just start a terminal from within that folder and start right to working on the setup of the install package. As mentioned earlier log out and before log back in gives options to pick different way to run the OS in. Lower resources or older style Linux Mint look & feel. Ya you should give it a try, If installing from W7 its a snap to install or uninstall. I found this a great help after messing up my 1st install with unneeded packages I was trying out. Gives dual boot menu at boot so you still have W7 to use is great. Just pick the OS from the boot menu you wish to have loaded for that moment.

I got an older version of linux mint on the one rig (just didn't keep up on the newest kernel) Im a regular linux user from the days of slackware and recoding and recompiling the kernel and XWindows manually and having a boot strap kernel in windows95 that is a basically a machine code version of linux that I can run from windows (basically a lilo kernel in windows) and Unux user so adopting wasn't so bad did lots of XWindows programming in my days I kinda think it was easier to install than ubuntu (at least for dual boot) ...even tho they are basically the same thing

Never tried to get GPUs Foldin' under Linux. I have always had difficulty trying to get the latest Nvidia drivers and my Monitor to be properly recognized in Linux too. I don't recall reading about anyone that Folds GPUs under the Linux OS, and Wine seems to have it's own issues from what I've seen posted. Just never seemed worth it to me, but I do agree that it would be sweet to Fold both SMP and GPU under Linux as an alternative to Windows.

I think I had it all set up before posting, but after downloading v7 for Linux It could never connect to a server to get work. Wasn't sure if it was a problem on my end or there is just no server/WU's for GPU & Linux/v7 yet? I didn't test for bigadv in v7 as I already had a BA running in terminal. I did notice problems after all the setup just after installing v7. I started getting freezing and stuff quit responding. Lost a BA at 48% done, were as I wasn't have any problems before.. So now on this rig I'm back at ground zero with uninstall of Linux Mint and also messed up my W7 OS so I had to wipe the HDD of that as well. Still showing a Linux option at boot even after it was uninstalled and clean W7 install. EasyBCD should fix the dual boot option tho.

Ok guys have another question, running Linux Mint 14 latest version. I'm trying to install the Nvidia driver for my video card. When I boot to root it will not let me install anything, says in Read Only when I run the package it needs to use the tmp folder but since its in read only mode it will not allow the use. So how would I get to read/write mode as root? The nvidia-linux-x86_64-310.32.run file tries to work in the GUI but says I have X client running to log clean as root. I didn't seem to have this problem with the little earlier version of 14 Mint. I may have to go back to it. Edit: oh ya I have this as a dual boot setup on my laptop with a SSD drive, being installed on SSD wouldn't have anything to do with this would it? I'm trying to get this working with this laptop as a test run before doing it on the already working Linux SMP systems.

Never mind, got it installed. Had to edit grub from inside the GUI with text, since it wouldn't allow it to be done as root with locked write mode. Once that was done and booted to text terminal mode it install without a hitch.  Of course I had to boot in safe video mode to re-edit the grub back to splash, now all is good. Lets see what kind of trouble I can get I into now. lol

No luck so far getting the GPU to fold with V7 in Linux. The card 460M does show as being there, but when I tell it to fold it can't get a assignment server to DL work from. I haven't looked into this closely as of yet, SMP is folding fine in Linux with V7 just as a test. I'll be using the console for smp and will look into console as well for the GPU witch I still prefer. Edit: 08:05:41:WU00:FS01:Connecting to assign-GPU.stanford.edu:8080 08:05:42:WU00:FS01:News: Welcome to Folding@Home 08:05:42:WARNING:WU00:FS01:Failed to get assignment from 'assign-GPU.stanford.edu:8080': Empty work server assignment 08:05:42:ERROR:WU00:FS01:Exception: Could not get an assignment I'd took some screen shots, but my print screen key doesn't seem to work in Linux and I haven't figured out how this is done yet. Not a priority at the moment. lol

After spending many hours trying to get gpu to run in Linux, I finally gave up. There are guides out there for gpu folding but they never worked for me (plus the guides are several years old). I think someone hacked a gpu2 client to make it work and is now useless.

Here, here...love Linux Mint and is my favorite of the distros.
Just wondering if you may have ran into this problem. On Linux Mint 14 after a week or so of folding I keep getting a pop-up saying low of HDD space. The rig becomes unstable and I start loosing WU's. I'm guessing is caused by the low HDD space. This was with a default size of 18GB moved to 20GB and even 25GB size now. What size do you use when doing a dual boot install of Mint 14? I can't understand why it starts to get the low HDD space pop-up when I haven't installed anything. I looked in the work folder of fah for old WU stuff that might not have been cleaned for take up space. This doesn't seem to be the cause. But something seems to be growing and taking up more and more HDD space. Since I don't know much about Linux and the way it works or may cache stuff I can't put my finger on a cause. Any help on this, anyone?

Wolf, I've always selected the largest size that Wubi provided (whether an Ubuntu or a Mint installation). Seems that largest size was around 30-32GB IIRC. I've never run out of disk space with a Wubi install of Linux and Folding on a HDD. The only time I ran into something similar to what you describe was when I was attempting to run Mint (and Fold) from a 16GB USB stick. It would work for awhile, but inevitably run out of resources and crash my Folding. Going back to HDDs, the problem never surfaced. These days, on most of my rigs, I've reverted back to discrete Linux installations on separate hard drives. I just have one Wubi install of Ubuntu on one of my rigs and it is in the 30-32GB range. On my other rigs, I have hot swappable disks, so I just pop-in Linux Mint when I need it, or pop-in Windows when I want to go that way. Wish I had an answer for you, but I haven't encountered that problem you are seeing with HDDs and Wubi. Hopefully someone else will be around that can speak to that issue. I've also made a lot of use of the Ubuntu and Mint Forums when I've gotten into weird stuff. Much of it has been self-imposed due to my own fledgling knowledge of Linux.

Thanks for the input. I haven't seen the problem since I went to 25GB install. If and when I run into it again on the other rigs I'll just up the allowed space to "fresh install" around 30GB since I don't have enough HDD's to have separate OS per HDD to do hot swaps. Thanks

the problem of most install is that most don't incorporate Swap partitions like the old days where we made separate partitions for swap space (linux can have two swap partitions for OS workspace - ie swap space = DDR mem size - for a complete swap out of ram space- x2 if you want two swaps) the new installer defaults to all in one - so if you didn't put up enough disk space you could be in an issue (since they share the same space now like M$) I however did a custom install and made swap partition in linux mint and made a significant drive space for the OS general rule should be if your using all in one - 2x DDR memory so for 16gig of mem you need 32 gigs for space min)

Thanks, I'll look into this on the next fresh install I have to do. I was thinking it might be something like a swap file growing and wasn't sure how all that is done in these Linux installs. What I been seeing is loss of space then the OS becomes unstable a couple times I can get by with fsck to fix the problem some what then the OS will complete crash or just be so bad only a new install works. Been hurting my folding from the down time "+new Install" plus the loss of work, one BA just last night at 92% done EUE. 40 something hours lost  Seems everytime I think things are running smooth it rears its ugly head.

This discussion of Swap file/partition size needing to equal Memory size has me thinking. Even on my discrete installations of Ubuntu 10.10 (64-bit), I've followed the typical advice from the Folding/Linux Guides that says "create a 4GB Swap Partition" as one of your two partitions on the HDD. I've followed that advice, but on all of my Linux-based Folding rigs, the Memory is at least 8GB and in some cases much more. My 4P has 8GB per CPU for a total of 32GB, but the Swap Partition set for Ubuntu 10.10 (64-bit) is only 4GB. I haven't yet run into the problem that Wolf has been seeing, and that may have more to do with having large enough amounts of HDD space for the system (EXT3 partition). But this discussion on Swap File/Partition size has me thinking about it. On my 4P, I'm wondering if I should kick that Swap Partition size up to 32GB to match the total installed memory. Increasing the Swap Partition size is no big deal on a dedicated Linux Rig because there's plenty of the HDD space that is never used given the small footprint that Linux/Folding requires. If I do make a change, I'll wait until I get onto the next string of endless 8101 WUs, oneunit it and see about making an adjustment. Edit: Maybe the suggestion of having Swap size equal Memory size dates back to when memory was a lot more expensive. I'm thinking that with larger memory sizes and low cost of memory, that the Swap size may not need to equal memory when we are talking about 8GB or larger memory sizes. If I understand the need for the Swap area, it pertains to when the OS/Applications need more area than the installed memory provides. But if Linux+FAH doesn't require levels exceeding 8GB or >, then the Swap area may be something that isn't used? Just thought I'd add this thought/question after thinking about this while thing a bit more.

note - the default swap on Linux is small less than 1GB the fact is if your hibernating/resuming swap must equal mem ptherwise you can get errors because on hibernate the memory is swapped prior to sleep if any errors occurs during this then it's unable to resume for folding I don't think you'll have a BIGBETA or Bigadv that takes more than 4GB so you wont hit a memory issue however as others have note if there is a memory leak/program fault on a program then you may wind up running out of room as others have said it all depends on your use if you use cad programs/simulation/heavy ram intensive progs then you might need more if you only using for folding then at least consider swap of 8GB or swap = mem (if you wish to hibernate) remember the OS eats some of the swap and you need a few GIGs for the WU linux os (running Xwindow/gnomedesktop with precision x and temp sensor and then F@H plus anything else running on the taskbar ) should eat at least 2-3 Gigs (it's not like console mode because you're using xwindows - memory hog) then add in the WU it might even be more than 3GB for the OS just leave enough for the OS and what room the programs may need for addtional space
