One more thing. The corrected version is actually in proposed: https://launchpad.net/ubuntu/+source/xserver-xorg-video-ati/1:18.0.1-2
I do not recommend enabling proposed in general, especially for something so crucial to the whole system. However, since it seems you're doing testing and not on a production system, it might be worthwhile to enable proposed and get the likely solution: https://wiki.ubuntu.com/Testing/EnableProposed -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-ati in Ubuntu. https://bugs.launchpad.net/bugs/1789071 Title: Invalid command stream with Radeon driver Status in Lubuntu Artwork: Invalid Status in xserver-xorg-video-ati package in Ubuntu: Fix Committed Bug description: Lubuntu 18.10 daily 08-25 I have a Pentium 4 SL7E8, 512 MB of RAM in a PT800CE-A from ECS and an ATI Radeon HD 4650 on AGP. The live CD boots up well to the Desktop, but then when I open an application, the part of the screen where the application should be hides the mouse cursor when I hover it, the Desktop background picture remains. Pressing screen 2, 3, 4 the hovering cursor is not hidden any more and pressing screen 1 the cursor is hidden again. When pressing screen 2, 3, 4 the screen button indicator remains on 1. I did a CTRL+ALT+F2 and lubuntu ENTER and: dmesg |tail -50 made a photo with my phone and attached it here. I am ready to run other commands you want after boot and attach the photo of the output here. I am sorry if this is not the right place for this bug.
