Pixelated screen on installation

ekhaled667 · 2017-08-26 06:43:32

I recently installed Arch Linux, when I booted from the usb device the text was pixelated.
I continued installation thinking maybe it's just the installation media, but when I booted for the first time the same problem persisted.
I installed X11, Intel driver and Deepin when started deepin everything was pixelated and it was laggy as hell, it even crashed.(Nano also crashed)
Here is some screenshots:

Here is what I tried to resolve this issue:
-I changed the resolution with no luck whatsoever.
-I uninstalled Intel driver.
- I reinstalled it and fell back to DRI 2 and uxa.

Nothing seems to fix the problem.
Note: I had Arch installed and working properly 10 months ago.
Note: The only screen that appears normal is the very first screen when booting from the disk (that loads the modules I think. The one that has green text, but the second screen that continues its work and has green text also is pixelated)
Note: This happened in the installation media, maybe it's a kernel problem with my video driver?

Believe me it's even worse the the screenshots.

What video driver(s)?

Not an Installation issue, moving to NC...

Intel HD 4600
I'm on Haswell
I tried disabling the acceleration and DRI, but none worked.
I set FreeTear True, but it didn't work.

You could try with the kernel's native modesetting. The Intel page on the wiki has the details.

I don't know what exactly you mean, but I just tried early KMS start and it didn't work.

Those are photos, no screenshots.
Does the problem manifest on actual screenshots as well?

@jasonwryan sorry for the late response tried that and it didn't work either.

@seth https://goo.gl/photos/7SoMsEkZ1Bsj1EFHA here is a link of a real screenshot, I viewed it on my phone it was displayed correctly, what does this mean?

The problem is somewhere between the scanout buffer and the display - either eg. an overdriven pixelclock (kernel bug or misconfiguration) or a hardware defect/interference.
Try
- booting some other live system
- booting in VGA mode (only applies to the linux console, not X11)
and see whether you get the same problem.

Also check dmesg for suspicious warnings/errors and at least post the output of "lspci -v" to specify your hardware.
Is this an integrated output or an external one?

@seth I booted to Solus which uses the kernel 4.12.7 and I found the same issue.
I booted to Ubuntu 16.04 which uses the kernel 4.4 and it worked perfectly, in fact I'm leaving this reply using Ubuntu.
I already have Windows installed and it works perfectly.

I'll try to fallback to an older kernel in Arch and see what happens.

The output of "lspci -v":
