Do you need additional information?

**varunendra** · February 18th, 2014

Welcome to the forums al3arbe1 !

Probably the first useful information you can provide is your native language. So what is your Native Language? Maybe we can find you a help source which you can be more comfortable with.

And since it seems to be a graphics issue from the screenshots, maybe a look at your graphics card and driver may help with the actual problem.

If you can boot into a usable graphics mode with a Live CD/USB, pleas post back the output of the following command to give us that info -

Code:

sudo lshw -C display

And with the installed system, try 'nomodeset' option as explained in the first post here : http://ubuntuforums.org/showthread.php?t=1613132

Feel free to ask if you have problem understanding the post or any of the suggestions.

So it occurs after working fine for a few hours?

If so, I would suspect the memory first.

If you get the Grub menu at boot time, where you can select to boot Ubuntu, Ubuntu recovery mode, Run memtest+ etc, select memtest+
If you don't get that menu by default, tap 'Shift' key as soon as the system starts booting (keep tapping the key until you get the menu). On some systems, it can be 'Esc' key instead of 'Shift'.

Run memtest+ at least 6-8 hours (better start it in the night or when you can leave it running that long), and see if it reports any "Fail" or hangs while running it. If not, the memory can be considered to be good. Otherwise it may be a memory leakage problem - means bad RAM.

It can also be a loose card (including RAM) or a loose cable, or another component that gets overheat after a few minutes/hours of working. But memory is the prime suspect in such cases where system boots fine, then suddenly crashes with weird graphics on the screen.

Leave memtest running continuously for at least 6-8 hours (recommended duration is 24 hours by the way, but 6 to 8 hours should be enough to prove it *reasonably* stable). It should Pass several passes in this duration. Successfully passing just 2-3 passes means nothing.

**al3arbe1** · February 21st, 2014

duration 38 hours (100 pass) is ok no errors

I think I am getting out of ideas, especially since I have rarely used dedicated graphics so far (I'm always happy with the onboard graphics), and have never 'Upgraded' Ubuntu (I always prefer a fresh install).

Please give us a complete detail of your hardware and drivers in use. To do so, run the following commands in a terminal -

Code:

sudo lshw -numeric -sanitize > Desktop/lshw.txt
lsmod > Desktop/lsmod.txt
cp /var/log/syslog Desktop/syslog.txt
cp /var/log/Xorg.0.log Desktop/xorg.txt

These will create certain "...txt" files on your desktop. Upload their contents on http://pastebin.ubuntu.com/ and post back the pastebin URL that you get after submitting it.

The graphics experts would probably also ask you to show them your Nvidia graphics related logs, but I don't know their names so can't say exactly which ones. Probably take a look in your /var/log directory and if you see any Nvidia graphics related log file, include its contents too in the above pastebin URL.

PS:
If anyone reading this thread have any ideas about how to find the problem or what to try, please join us. Thanks!
