If this you are using a 5.10 kernel, try rebooting on a 5.9, for me it fixed the issue (20 days and counting). Regards, -- Nicolas George signature.asc Description: PGP signature

There are two DDX drivers applicable to your (>9 years old) Sandy Bridge IGP: intel modesetting If xserver-xorg-video-intel is installed, typically its provided intel DDX will be employed. Without it, normally modesetting will be employed, a component of the server .deb, and the upstream default. xserver-xorg-video-intel is informally deprecated, getting mostly only bug fixes for the past 7 years, and no official release since then. A look through /var/log/Xorg.0.log should make it obvious which is in use, lots of intel(0) strings or lots of modeset(0) strings, but not both. Sometimes one may find an override specification either in /etc/X11/xorg.conf or in /etc/X11/xorg.conf.d/25-intel.conf or other xorg.conf.d/*conf. Try switching from one DDX to the other. Which kernel, 5.10.x, or 5.11.x? If the latter, try a 5.10.x if you can, or at least an older 5.11.x. In none of this helps: pastebinit /var/log/Xorg.0.log and share here the resulting URL. If /var/log/Xorg.0.log is absent, look in ~/.local/share/xorg/ for it. -- Evolution as taught in public schools, like religion, is based on faith, not on science. Team OS/2 ** Reg.

Video hangs on ThinkPad X220 T
Hi, I'm having what I suppose are random (not frequent) video server hangs. This is a ThinkPad X220 T with Debian Testing and: 00:02.0 VGA compatible controller [0300]: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller [8086:0126] (rev 09) I'm using IceWM here, but not sure if that's relevant. The symptoms are that randomly screen image gets frozen, but with some (also random) little variations, but mostly frozen, meanwhile everything else in the system seems to keep working fine, even the WM keyboard shortcuts (but you have to imagine what's happening, of course). Only thing I found that seems apparently relevant in both `sudo journalctl` and `sudo dmesg` is: debian kernel: i915 :00:02.0: [drm] GPU HANG: ecode 6:1:85fc, in eadedCompositor [10433] debian kernel: i915 :00:02.0: [drm] Resetting chip for stopped heartbeat on rcs0 debian kernel: i915 :00:02.0: [drm] eadedCompositor[10433] context reset due to GPU hang Any idea what to do/where to look? Sometimes you get logged-off from your session and put back to the DM log-in screen. Other times you have to kill the WM from another tty and then re-log. Everything else seems ok. Thanks a lot in advance for any help.
