I downloading & booted Xubuntu 20.04 daily and played there. same hp dc7700 (c2d-e6320, 5gb, nvidia quadro nvs 290) on same box. adding xscreensaver & using 'flurry', I got the same jerky/choppy response here once packages added & running.
I could see the xscreensaver dialog box where I click 'preview' (approx correct position on screen but on wrong display??!!) when it jerked (or I described as black-white-blocky-bad-signal in original post; I'd not use those words now). Yes it's somewhat like a bad signal on tv, but I do get the same response here on Xubuntu 20.04 daily. -- You received this bug notification because you are a member of Ubuntu-X, 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) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/1855220/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
