I've been using Ubuntu Mate 19.10 for at least a half year, and everything was perfect until 2 weeks ago I updated all packages (apt update && apt upgrade). I suppose that it was some big update, because a lot of packages got new versions, my display drivers were updated, after restart I had to enroll mok before booting the system, etc.
But here comes the problem: after this update a lot of interface items became much smaller. I can see that running application icons on my top bar became smaller, their number was increased and the fonts became much thinner. And while for the most applications nothing really changed (maybe fonts became a very little bit smaller), some applications became impossible to use. For example all elements and fonts in my JetBrains IDEs became so small I can't even read them at all. I contacted jetbrains support, but it looks like it's some kind of a system issue.
Worth to mention: I use laptop (HP envy 15.6", 1920x1080, GM108M [GeForce 930M]) and an external Dell monitor (27", 1920x1080). If I unplug my external display and then reboot - everything becomes normal. Moreover, if I plug in my external monitor after system is booted - everything is also OK.
Since I didn't change any configuration, I'm 100% sure that the last update was the reason of the issue. That's why I'm looking for a way to restore my previous state.
I also tried:
- Switching secure boot on and off
- Changing drivers version (NVIDIA 440, NVIDIA 435, NVIDIA 390)
- I even updated to 20.04 LTS when it became available
But none of the above helped. Right now I have to boot without my external display plugged in and plug it in after the system is booted, I can live with that, but it's very confusing.
