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 0000:00:02.0: [drm] GPU HANG: ecode 6:1:85fffffc, in eadedCompositor [10433] debian kernel: i915 0000:00:02.0: [drm] Resetting chip for stopped heartbeat on rcs0 debian kernel: i915 0000:00:02.0: [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.
