I noticed this today on a QA-test install of Lubuntu (jammy) daily on - hp dc7700 (c2d-e6320, 8gb amd/ati rv610/radeon hd2400 pro/xt)
this box & old & slow, and during install xscreensaver kicks in (more than once!) & choppy/strange video was evidenced with xscreensaver/flurry of little/no importance though (in my opinion; only impacts a few video cards; and if it was me; I'd just select another screensaver post- install (I do usually anyway)... not sure if even worth mentioning on 22.04.2 release notes -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-nouveau in Ubuntu. https://bugs.launchpad.net/bugs/1855220 Title: xscreensaver is choppy on lubuntu 20.04 daily qa-test (flurry) Status in lubuntu-default-settings package in Ubuntu: Fix Released Status in xserver-xorg-video-nouveau package in Ubuntu: Confirmed Bug description: Lubuntu 20.04 daily QA-test on hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290) Displays have been adjusted to my setup (one above the other) but I doubt this is an issue I suspended system, waited, pressed ESC to wake & it resumed to xscreensaver, but 'flurry' was chopped and showing white/black patches on display as if glitching... I touched mouse & my session removed. opened xscreensaver & preview - yep glitch there too... changed to 'fliptext' & no issues, but flurry is very jerky with image switching to almost-blocky-bad-signal (I think it's alternating between showing something else, text; it seems to vary on what I've had on screen before screensaver is loaded & continuing to show xscreensaver..) attempts to screengrab with delay have failed (just capturing black screen).. `lshw -C video` reports I'm using nouveau. This issue may not relate to 'xserver-xorg-video-nouveau', but I suspect it's there. I've performed this test a number of times on various boxes without issue (will do so again once I shutdown this).
