It seems to have helped for me.
Hi all, I'm the reporter of this bug https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1388612 that was redirected here. I've tested the fix on my machine updating the Xorg stack from https://launchpad.net/~xorg-edgers/+archive/ubuntu/ppa A packaged version of Mesa with the fix was released there yesterday only. Unfortunately, even though I'd like to, I'm not able to update the system by myself as soon as a change is committed. Cloning the Mesa repository, building and installing it is not enough, right? Is there a "faster" method than the one I've used? Anyway, glmark2 ideas benchmark works fine now but, in my case, the issue is not solved yet. An application written by myself using SDL (https://www.libsdl.org/), that before the fix used to cause the hang most of the times, now terminates due to a failing assertion in Mesa. The most frequent is: SDLApp: ../../../../src/mesa/vbo/vbo_exec_draw.c:222: vbo_exec_bind_arrays: Assertion `exec->vtx.bufferobj->Mappings[MAP_INTERNAL].Pointer' failed. Sometimes this happens: SDLApp: ../../../../src/mesa/vbo/vbo_exec_draw.c:278: vbo_exec_vtx_unmap: Assertion `exec->vtx.buffer_ptr != ((void *)0)' failed. The application works fine on another machine with a different chip. The billard game FooBillard++ (http://foobillardplus.sourceforge.net/) still causes the hang immediately. The workaround of using always_flush_cache=true and always_flush_batch=true doesn't work with my application nor with FooBillard++. I was just able to use it to let ideas benchmark running fine prior to the fix. I've not tested Chrome yet but I can do it if it can be useful. Thank you Kenneth for the fix and for any further help. I'd really like to use Linux on this machine for my developments. If I can help somehow let me know. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1388612 Title: [GM965] GPU lockup running OpenGL applications on Dell Vostro 1510 Status in Mesa: Fix Released Status in xorg package in Ubuntu: Confirmed Bug description: Hello, I'm suffering a GPU lockup problem with Ubuntu 14.10 64-bit on a Dell Vostro 1510 laptop with Intel graphics. The problem used to arise also with Ubuntu 14.04 and is always reproducible with glmark2 on the LiveCD. Just to run the "ideas" benchmark of glmark2 to trigger the lockup in few seconds (glmark2 -b ideas). Other OpenGL applications also causes the lockup (e.g. FooBillard++, my self-made SDL applications). Memory test passed, BIOS at the latest version. Don't know if the following is a good point but I think that the problem is not caused by a failing hardware because it works fine on Windows. I tried with the latest Intel upstream kernel (http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel- next/current/) and upstream X.org (https://launchpad.net/~xorg- edgers/+archive/ubuntu/ppa), no change. [Personal Notes] I'm new to Ubuntu's world, I hope I've done things right, if not please tell me and I will resend the report or supply more information. I've created the bug report with "ubuntu-bug xorg --save" from another machine via SSH while the sick machine was frozen. It seemed to me more logical than using ubuntu-bug directly when the system is working fine. I've collected other information via SSH during the same lockup: dmesg, Xorg.0.log, i915_error_state. The latter was added as attachment.
