I still have flickering problems with the X1300, kernel 5.4, Ubuntu 20.04. $ lspci | grep Radeon 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RV515/M52 [Mobility Radeon X1300] $ uname -r 5.4.0-33-generic $ lsb_release -r Release: 20.04
The display is a laptop panel on a Dell Inspiron 6400. $ xrandr LVDS connected 1280x800+0+0 (normal left inverted right x axis y axis) 331mm x 207mm 1280x800 60.04*+ When the display wakes from sleep, it is "random" whether the flickering occurs or not. My workaround: use xrandr to force mode switches until the flickering goes away. For example, run the following command one or more times: $ xrandr -s 1 && xrandr -s 0 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1791312 Title: ubuntu 18.04 flickering screen with Radeon X1600 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1791312/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
