Now 24.04 doesn't see my M5000M graphics adapter most of the time. When it does it won't configure the video output correctly. The screen is 99% - white with a hint of a Ubuntu top of screen status bar showing. + white with a hint of a Ubuntu top of screen status bar showing. (see + attached photo). Sometimes the display is top 30% all white and the rest black. - In one case the sync setting was incorrect but changing it back to 100Hz - failed to solve the problems. + In one case the sync rate setting was incorrect but changing it back to + 100Hz failed to solve the problems. This new bug is in addition to the suspend\hibernation problem when starting up 24.04 with the laptop lid shut. In this instance I normally lift the lid slightly to get the laptop to wake up again and upon closing the lid I used to get the Ubuntu GUI displayed on the ext monitor. This behavior no longer occurs, i.e. the ext monitor ends up black or white as described above. Sometimes even the laptop internal graphics adapter shows a totally black screen as well. In one case I had to totally power down my ext monitor because it had got so screwed up by 24.04 that even if I booted into Windows 10, Win10 failed to detect\use the monitor!

Ubuntu 22.04.5 LTS works perfectly on my hardware setup.
