Graphics are fine in Windows 7. I have had the motherboard and CPU replaced, the issue still exists. Memory tests fine. Symptoms: 1) The screen is covered in small wrong-color squares, almost like a corrupt JPG. Some screen elements render fine (e.g: the twm menu) while others are unreadable. Screen elements are not always drawn over when they go away. See the pictures attached for examples: 2) Driver hangs on any 3d type activity. glxgears, for example, will cause the screen to basicly freeze. The driver will then reset (as shown in dmesg). xorg-edgers drivers do not appear to freeze, but glxgears exits with "intel_do_flush_locked failed: Input/output error". glxgears registers 0.163fps or lower. 3) The image seems to display properly using the VESA driver. (Boot gentoo live-dvd with -nofb option) 4) With ubuntu and the xorg-edgers PPA, the corruption is present using both the "uxa" and "sna" AccelMethod options in xorg.conf 5) Sometimes, switching to a VT and back will clean up the image for a moment (i.e. until something moves) Also, after glxgears crashed with the error above, most applications were readable. However, redraw problems were still rampant, and trying to run glxgears again gives the do_flush_locked error above I have confirmed these issues are present when booting the following distros: Linux Mint 13 (64bit) Live-dvd Ubuntu 12.04 (64bit) Install CD and Standard install Gentoo 64bit Live-DVD 12.1 (regular boot, -nofb boots into vesa mode) Ubuntu 12.04 with xorg-edgers PPA (As of July 22, 2012) Hardware: CPU: Intel i5-3470 Chipset: Intel Z77 (M/B: Asus P8Z77-V, bios rev 1205) Memory: 2x 8GB Patriot G3 DDR3-12800 1600mhz Monitor: VGA connected CRT or HDMI connected LCD Currently Running kernel: Linux Hoita 3.5.0-5-generic #5-Ubuntu SMP Wed Jul 18 07:35:23 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux Installed packages (Up-to-date with xorg-edgers-ppa as of July22, 2012): linux-generic 3.5.0.5.5 xorg 1:7.6+12ubuntu1 libdrm2 2.4.37+git20120713.992e2afd-0ubuntu0ricotz~precise libgl1-mesa-dri 8.1~git20120720.cdad337f-0ubuntu0sarvatt~precise xserver-xorg-video-intel 2:2.20.0+git20120720.f92a64dd-0ubuntu0sarvatt~precise Reply at: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/1031784/comments/0 ------------------------------------------------------------------------ On 2012-07-23T05:23:51+00:00 Jonathan wrote: Created attachment 64521 Picture of screen artifacts (driconf open in twm) Reply at: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/1031784/comments/1 ------------------------------------------------------------------------ On 2012-07-23T05:24:14+00:00 Jonathan wrote: Created attachment 64522 Xorg log Reply at: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/1031784/comments/2 ------------------------------------------------------------------------ On 2012-07-23T05:24:36+00:00 Jonathan wrote: Created attachment 64523 dmesg output Reply at: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/1031784/comments/3 ------------------------------------------------------------------------ On 2012-07-23T05:25:10+00:00 Jonathan wrote: Created attachment 64524 Listing of installed packages and versions Reply at: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/1031784/comments/4 ------------------------------------------------------------------------ On 2012-07-23T05:26:04+00:00 Jonathan wrote: Created attachment 64525 /etc/drirc Reply at: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/1031784/comments/5 ------------------------------------------------------------------------ On 2012-07-23T05:26:32+00:00 Jonathan wrote: Created attachment 64526 glxinfo Reply at: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/1031784/comments/6 ------------------------------------------------------------------------ On 2012-07-23T05:27:09+00:00 Jonathan wrote: Created attachment 64527 i915 error state Reply at: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/1031784/comments/7 ------------------------------------------------------------------------ On 2012-07-23T05:28:27+00:00 Jonathan wrote: Created attachment 64528 lspci -vvv output Reply at: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/1031784/comments/8 ------------------------------------------------------------------------ On 2012-07-23T05:29:27+00:00 Jonathan wrote: Created attachment 64529 intel_reg_dumper output Reply at: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video- intel/+bug/1031784/comments/9 ------------------------------------------------------------------------ On 2012-07-23T05:34:41+00:00 Jonathan wrote: Turns out that the GPU is hanging with the latest xorg-edgers packages, same as before (see the dmesg output).

The Bios has a "Normal" setting in basic mode, which is supposed to disable all the overclocking features. It was the first thing I tried when I got the new motherboard and noticed the problem. In advanced mode, it gives you a LOT more overclocking options, but I'm not into overclocking, so I haven't used many. Right now, almost everything is set to factory default except the RAM. It's set to 1600MHz, which is what the RAM is rated for. Previously, it was 1333MHz, and the problem still existed. I have not tried fiddling with any of the more advanced settings. Right now, mostly they're all set to auto. If there is any particular change you would like me to make, please let me know. Thanks!

However, when launching Unity (logging in), the computer crashes HARD. Previously, I could switch to a VT, and kill X. Now, I cannot. (I needed to ssh into the system to get these logs) Also, glxgears crashes without showing anything.
