Display weird behavior (resolution?) on startup. Messed up screen

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”? :stuck_out_tongue:
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 !!!

Cheers !

Is xf86-video-intel installed? We could also use the output of inxi -Fxxxza --no-host

Yes xf86-video-intel is installed

That would be the output of inxi -Fxxxza --no-host

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.

Removing the package lead to: failed loading light display manager

So you still have the USB installer?

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.

Some graphics related or kernel updates may sometimes cause trouble.
Have you tried using the LTS kernel?

1 Like

yep unfortunately i did :frowning:

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.

Oh, Rick is coming this way! :slight_smile:

Have you tried adding i915 to the MODULES=" " section in the /etc/mkinitcpio.conf

1 Like

hey, thank you all for your help, much appreciated!

so i915 wasn’t in the MODULES section of mkinitcpio.conf
I did add it (so the line would look like that: MODULES="crc32c-intel i915"

and it is still the same behavior :’(

Okay I don’t think it will hurt having it anyway. Maybe try some kernel parameters such as


You can add that to the default grub command line in /etc/default/grub and update grub with
sudo grub-mkconfig -o /boot/grub/grub.cfg

i can’t remember if i tried it before, so i just did add the line and rebooted

→ still no luck :confused:

i guess i’ll try other kernel instructions (and combinations of it) as described in the endeavour installaion guide. (i think i did)

and @manuel i will try sddm right now (i tried some other dm, can’t remember if all of them)

Well if you are game i think you’ll need to try some other kernel parameters

i tried some of them (the exemples listed in endeavour guide at once (is that a mistake ?) with no results.

i have to check sudo modinfo -p i915 for the complete list

well, still no luck

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?
