UPDATE: 11h41GMT Fri 12 Jun 2020 Rob Jarvis: Freeze occured again today, second time since original report. This time I was able to Alt+F2 and switch into the desktop in focus in the 4-part desktop 'palette' view. This killed the freeze. The freeze seems to be associated with 2 factors which may be related, or not:
1) a having desktop with windows which overlap out of the visible area. When swithcing into dektop palette mode the previously out of sight bits of the windows in the one desktop then show as overlapping into the adjacent desktops in the palette view (clearly all 4 are mapped into the same large pixel space). If I try to tidy up the overlaps in the palette view I am likely to hit a freeze. If I return to the single desktop and tidy up the windows by reducing their size and ensure all fit into the active desktop, then return to the palette view, I can then shuffle the smaller windows from one desktop to another without hitting a freeze, unless... 2)... I drag a window diagonally, say from Top-left to bottom right, so that the subject window traverses more than 2 desktop areas. Then I am more leikely to see the freeze... it seems. If I drag a desktop completely from that top left to top right and then wholly from there to bottom right it seems to stay well behaved and doesn't freeze.. so far. ==> END OF UPDATE 11h41GMT Fri 12 Jun 2020 -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1882112 Title: [radeon] Screen freeze Status in compiz package in Ubuntu: Incomplete Status in xorg-server package in Ubuntu: Incomplete Bug description: This may be correlated to the move to Bionic Beaver(?) LTS, now 18.04.4. It may also be correlated to getting low on disk space on my system drive (50GB SSD) and putting pressure on swap space. e.g when system HDD <= 1GB. My secondary HDD is a 1TB USB spinning device that sometimes seems to go into sleep mode and then fails to rapidly respond to IO request or may be is in a 'hot IO' state. On my Bus I have a low capacity HDD that is essentially unused because it rarely comes ready when I boot. If it is partially alive it is conceivable that it might be chattering and so competing for IO interrupt handling bandwidth? The problem only occurs when I have selected the desktop management tile from the 'side tray' and if I then shuffle or better align the windows inside one of the four desktops so as to stop them running into the neighbouring desktop area. Particularly, it seems to me, when at least one of the desktops is quite busy with windows open in it and the overlapped desktop has a few also. The fewer windows in total across the desktops the less likely it seems that rearranging a few will have any bad effect. When the freeze occurs then 60%(?) of the time it ends in a 'big red switch' reboot. The cursor stays active but ineffective. Keyboard combinations, like Alt+W, will sometimes succeed in bringing up to full screen mode and active the desktop that was in focus and constitutes a recovery. Other times, and keys, will delete focussed windows in the focussed desktop, and Tab will move focus around the 4 desktops. SHIFT+Print Screen also executes but just takes the whole screen and dumps it somewhere I haven't yet located... with sound effect. Hope this helps... I am not at fully at home with Ubuntu/Linux yet... having spent a lifetime on glasshouse legacy IBM mainframe field systems engineering. I am making myself more system disk space meanwhile, and while extract my old Maxtor. It would be nice if I didn't have to up my system disk to hundreds of GB! best regards, Rob ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: xorg 1:7.7+19ubuntu7.1 ProcVersionSignature: Ubuntu 4.15.0-101.102-generic 4.15.18 Uname: Linux 4.15.0-101-generic x86_64 .tmp.unity_support_test.0: ApportVersion: 2.20.9-0ubuntu7.15 Architecture: amd64 CompositorRunning: compiz CompositorUnredirectDriverBlacklist: '(nouveau|Intel).*Mesa 8.0' CompositorUnredirectFSW: true CurrentDesktop: Unity:Unity7:ubuntu Date: Thu Jun 4 11:31:56 2020 DistUpgraded: Fresh install DistroCodename: bionic DistroVariant: ubuntu ExtraDebuggingInterest: Yes GpuHangFrequency: Several times a week GpuHangReproducibility: Occurs more often under certain circumstances GpuHangStarted: I don't know GraphicsCard: Advanced Micro Devices, Inc.
