[Bug 732304] Re: Intel sandy-bridge dual-head GPU hang
** Description changed: Binary package hint: xserver-xorg-video-intel Just upgraded my PC to natty as of today (alpha-3) and moved the HDD to a new PC barebone based on Intel Sandy-bridge (Core-i7 2600K) with two monitors connected. After configureing xorg.conf and booting, kdm came up fine, but the session-type menu top-half is unreadable (garbled). After logging in (Desktop effects disabled), everything seems to work for a few seconds with only minor display glitches, but after a random time, or at certain actions (like entering a URL in chrome), the X server freezes. Sometimes it freezes forever, and sometimes it comes back after a few seconds (display goes black for a while). The system keeps running fine, and dmesg shows this: ...

Just wanted to confirm the problem.

With the latest kernel and intel driver updates as of yesterday (12.04.2011) the garbled menus problem appears fixed.

[Bug 732304] Re: Intel sandy-bridge dual-head GPU hang
I can confirm that it now is working without the xorg.conf. I also got dual screen working, how ever Kubuntu seems to forget this settings after every X server restart. I am fixing this with the following lines in /etc/kde4/kdm/Xsetup: xrandr --output HDMI1 --primary xrandr --output HDMI1 --mode 1920x1080 xrandr --output HDMI3 --mode 1280x1024 xrandr --output HDMI3 --left-of HDMI1 I am sure there would be a better solution but that’s how it works for me.

The option with the Option Shadow true in the xorg.conf works for me on Kubuntu 10.10 as well as in 11.04 beta 1. The attached xorg.conf has a lot of data which is not really needed.

@Robert, I tried with your kernel, and it doesn't make any difference.

[Bug 732304] Re: Intel sandy-bridge dual-head GPU hang
@yope, I see you're running a somewhat older kernel. Can you please update to current natty and check if you can reproduce the issue there? I ask because we've fixed several quite commonly encountered gpu lockups between the kernel this is reported against and current, so want to make sure what you saw is not just an already solved issue. ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: New = Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/732304 Title: Intel sandy-bridge dual-head GPU hang -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 732304] Re: Intel sandy-bridge dual-head GPU hang
@Bryce, I was running up-to-date versions of everything when I initially posted. I just updated and commented-out the shadow option in my xorg.conf file as you suggest, restarted the X server and until now, no lockups. But the display glitches are back. See the attached screenshot. Should I file a new bug-report for the glitches? ** Attachment added: Sample screenshot showing glitches https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/732304/+attachment/1939479/+files/corrupted-menu.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/732304 Title: Intel sandy-bridge dual-head GPU hang -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Yeah semaphores were disabled in the final 2.6.38 release so that hang will be gone.

@Robert, mind looking at this one? I recall you mentioned today seeing something that sounded similar to this bug, perhaps you already know of a patch to test? ** Changed in: xserver-xorg-video-intel (Ubuntu) Assignee: (unassigned) = Robert Hooker (sarvatt) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/732304 Title: Intel sandy-bridge dual-head GPU hang -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Extra information. Since today I have added Option Shadow true to the device section in xorg.conf and since that, the artifacts and visual glitches seem to be gone, and I have yet to see the X server freeze. Of course this is not a solution, but merely a workaround.
