Re: [qubes-users] Unsolicited feedback on qubes-issue #2455
I ran into a weird (and not consistently reproducible) issue with my 2-monitor setup (UHD main screen + FHD secondary) adjusting the 'display' settings (changing the alignment of the 2 monitors). When I 'moved' the FHD screen from right of the upper right quad of my UHD screen, to 'below' the lower left quad, and then left of the upper left quadrant, but not aligned with the top border (about 300px lower), then to roughly vertically 'centered' of the right, I could no longer click on any of the buttons / tabs at the top of my firefox instance (which is snapped to use the left half of my UHD monitor), and the mouse 'clicked' in different spots than where the cursor was located. I had to restart the VM to 'fix' this. Happened twice, but not since. -- You received this message because you are subscribed to the Google Groups "qubes-users" group.

Ok, this problem happened again, and always when starting monodevelop. Now I collected more logs, and tried to fiddle a bit with qubes-guid. In dmesg there's nothing interesting apart from 238 repetitions of this line just before the crash manifested with all windows from that VM disappearing: [ 77.469369] U2MFN_GET_MFN_FOR_PAGE: get_user_pages failed, ret=0xfff2 Before this repetition of lines there is only the Fedora 25 (Workstation Edition) login prompt. The full content of guid log is short: -snip- Icon size: 128x128 invalid PMaxSize for 0x340001c (32767/32767) invalid PMaxSize for 0x340001c (32767/32767) invalid PMaxSize for 0x3400025 (32767/32767) invalid PMaxSize for 0x3400025 (32767/32767) invalid PMaxSize for 0x3400025 (32767/32767) ErrorHandler: BadAccess (attempt to access private resource denied) Major opcode: 130 (MIT-SHM) Minor opcode: 1 (X_ShmAttach) ResourceID: 0x340003b Failed serial number: 1294 Current serial number: 1295 -snip- And that's all of it. This run was from a freshly started VM, where only Firefox and Thunderbird were started before monodevelop. I'm starting to get convinced that windows that appear and suddently disappear after a very short amount of time can be a problem for gui-daemon. After the crash I tried to open a shell to restart the daemon (later I tried to just restart the daemon from dom0) but without luck: dom0$ qvm-run --pass-io work /bin/bash [here the windows from the work appVM briefly returned on screen, a terminal appeared too, then everything from that vm disappeared again in a couple of seconds. No output in dom0 terminal, so I killed this qvm-run instance] dom0$ qvm-run --pass-io work /usr/bin/qubes-gui Running command on VM: 'work'... --> Starting Qubes GUId... Connecting to VM's GUI agent: .exiting ERROR(work): Cannot start qubes-guid! dom0$ qvm-run --pass-io work "/usr/bin/systemctl restart qubes-gui-agent" Running command on VM: 'work'... --> Starting Qubes GUId... Connecting to VM's GUI agent: .exiting ERROR(work): Cannot start qubes-guid! And that's when I gave up... The way out is to restart the VM.

I'm sorry, but I was in a semi-hurry and did not keep the logs. My plan-B was to restore everything from a backup in case the upgrade produced some catastrophic situation, and since a mere VM reboot fixed the situation, I did not keep the logs but only some fragments I deemed important.

It may be nice to have a fallback handler for qubes-guid crashes, if the X architecture permits, that restarts the daemon and restores windows redirection to dom0.
