i recently upgraded CPU from T2400 to T7200 to have 64-bit support to be able to install Ubuntu 18.04 64-bit. after fresh install i got very laggy login and no ubuntu boot loading screen, very corrupted login screen that user name and other informations were not visible and i typed password without seeing password box, then corrupted desktop. i ran "sudo apt update && sudo apt full-upgrade" to check if it s driver or update issue but problem is continuing. i also tested kernel 4.18.0-15 and 5.3.0-.50300rc3 but still same problem.

Fresh installed Ubuntu 19.04. setup gone fine. no login or boot screen corruption. just at first time logged in there was corruption on desktop same as i faced 18.04. after i ran "sudo apt update && sudo apt full-upgrade" and rebooted, desktop is fine. but there is no transparent effects on top bar and dock, just black background.

also noticed that i cant watch Netflix. Firefox version is 68.0.1 which most recent version in Ubuntu and suppose to play movies in Netflix. i am getting Error Code: F7111-1331. cant play videos on other html5 based website. just youtube working fine.

another issue, sound is too low even i enabled Over-Amplification.

Login screen corruption and screen flickering as in the screenshot: https://launchpadlibrarian.net/436378920/file-3.jpeg is happening while on docking station attached to external monitor (Lenovo ThinkVision LT2252p)

[Mustafa Erdogan (muerdogan)]

installed Unity desktop to 19.04 and LightDM for login screen and no more screen corruption on login screen after installed lightdm and unity desktop but still there is no transparent effects. top bar at desktop and terminal interface is white.

screen flickering continuing on docking station attached to external monitor.(attached via DVI Port)

[Mustafa Erdogan (muerdogan)]

OK. recent update is this, i re-installed 18.04 and when i first booted after installation desktop wallpaper was corrupted again. then i changed desktop wallpaper and there was no corruption. i installed mesa drivers, some codecs and rebooted again. then same thing happened that desktop wallpaper corrupted. then i changed wallpaper again. something is corrupting desktop and login screen i guess. i have transparent effects at top bar and dock.

[Mustafa Erdogan (muerdogan)]

screen flickering and login screen corruption problem with docking station and external monitor still exists.

[Mustafa Erdogan (muerdogan)]

Ubuntu 18.04.2-64bit

i noticed that wallpaper corruption is happening mostly in ubuntu official wallpapers such as purple disco dingo wallpaper. when i change to standard wallpapers like a photograph corruption not happening.

Lock screen is also corrupting same as default wallpaper (related screenshot is in attachment)

Additionally ubuntu-gnome default on screen indicator symbols such as volume control dont appear.

[Mustafa Erdogan (muerdogan)]

another issue that on dock, icons getting cut as you see in attached screenshot in "Text Editor" and "Show Applications" icons, half is cut. it is happening randomly to other icons too.

9 years ago similar problems have been reported as well >> https://bugs.launchpad.net/ubuntu/+source/linux/+bug/541501 it seems it is ATI driver problem more than being old machine.

[Mustafa Erdogan (muerdogan)]

installed Unity Desktop and no desktop/login/lock screen corruption happening on the laptop with no external monitor. but On Screen indicator symbols dont work (example screenshot for on screen indicators: https://launchpadlibrarian.net/424611485/Screenshot%20from%202019-05-20%2023-32-46.png)
