Hello,
First of all, thanks a HUGE lot for that wonderful distro!!
I’m already sorry cause i dunno if i should post here or in bug section, or noob or… “try harder”?
I’ve browse several leads to try to “fix” my problem, unsuccessfully…
So, here’s the story…
I have an install on an HDD, works fine.
Bought an SSD (NVMe), installed on it → display mess on startup (after grub, starting at the login screen (lightdm i guess))
Got another SSD (SATA)(not at all because of that indeed), installed on it → same problem with displayed screen resolution (or is it?)
Well, i don’t think the kind of drive have anything to do with it indeed, probably installation related.
So, as you can see on pictures, the display “switch” to that weird resolution on startup, after choosing an grub entry, when the login screen appears, and stays like that… seems to be consistent on each startup with the last install, but was more random (sometimes no problem with the display) on the previous one.
Anyway, a workaround is to put the computer to sleep, then wake it up, and everything is fine, no more weird distortion on the screen. This “solution” works perfectly…
If anybody could lead me to where I should investigate… it would be so sweet and MUCH appreciated !!!
You could try to remove it as it sometimes causes issues like this. I wouldn’t without a back-up plan. I can’t guarantee you wont reboot into a black screen.
I’ve seen it, thanks a lot, i don’t know if i tried the right troubleshooting, i did try TearFree and the Screen flickering without success. i also tried to force keeping the resolution in grub config as describe in the installation guide.
Maybe i should try more “tweaks” in the modprobe…
It’s weird cause i still have the up to date Endeavour HDD install on that machine and never had this problem with it.
it’s also weird that asa it’s put to sleep and resume the screen is fine again.
i don’t really get what it’s doing, looks like it’s trying to display the correct resolution (or not…) on a “bigger” screen than it is (the bottom and right parts are outside the screen, not sure the pictures show that well) [edit: only the right part of the display is missing, height looks ok…euh, well it doesn’t ^^ ]
Not sure if it helps anything, but changing display manager to sddm might be worth trying.
But more probably some graphics driver related setting or kernel parameter could help.
I’m not good at them, so hopefully someone with more insight will help.
No i don’t think it hurts but if you find something that works then you’d have to remove one at a time to figure out which one is the correct one. I’m sure there could be conflicts also but you’d probably see that in a hurry. Usually removing the fx86-video-intel is what works. But you need to be running on the kernel module not the Intel so you would need to make sure it’s not loading intel. Have you tried nomodeset?
