[SOLVED] corrupted display after graphical mode

kdiablo · 2014-11-03 22:13:34

Hello,
I am new to ArchLinux.
After Installing the system, I followed the instructions on wiki.archlinux.org and managed to launch the graphical mode (xterm and even KDE).
However, it seems that after exiting the graphical mode, my screen is corrupted (I suspect that text console becomes corrupted during launching graphical mode but it is not visible until returning to text mode).
The Linux itself works properly (f.ex. alt+ctrl+del works ok).

I added only exec xterm to the ~/.xinitrc file and I am using MSI netbook with intel graphics card.

I attached two pictures describing the problem:

And logs from xorg:

I would be very helpful for any help!
Cheers,
KK

Welcome to the forums. If I'm reading that log correctly, it looks like you are using the Vesa driver - I would not recommend this, vesa is finnicky at best (often it just fails all together in my experience). So rather than figure out how to get Vesa to work well, just get the right video driver.

The beginner's guide gives the commands for checking what your video card is and which driver to install. Have you done that? Which driver did you intend to use?

If your video hardware is not supported by any driver (almost certainly not the case) then still I'd not recommend Vesa, but either fbdev or mode-setting.

Do you start X manually? If so, what happens if you blindly type 'reset' after quiting X? Are other ttys also corrupted?

Hi,

I've just reinstalled xf86-video-intel (based on https://wiki.archlinux.org/index.php/Xorg):

pacman -S xf86-video-intel

but nothing changed.
Is there a better way to reinstall the driver?

I start X manually, via startx.
After blind 'reset' screen seems to react. It becomes darker and only the first line has white spots. But it is still corrupted.
All other terminals become corrupted once I start X.

It seems that after starting X, a driver is started that can handle graphical mode but can't deal with terminal, it's quite strange.

That is all that should be needed to install the intel driver - but X isn't using it. Are you sure that's the right driver for your hardware? What is the output of `lspci | grep -i vga`?

@kdiablo
Most intel cards use intel drivers, but see the note on https://wiki.archlinux.org/index.php/Intel_graphics -> https://wiki.archlinux.org/index.php/Poulsbo and https://wiki.archlinux.org/index.php/Intel_GMA3600

kdiablo · 2014-11-05 22:14:05

I checked my graphics card as you advised.

# lspci | grep -i vga
00:02.0 VGA compatible controller: Intel Corporation Atom Processor D2xxx/N2xxx Integrated Graphics Controller (rev 0b)

I also found in the netbook's specification that:

CPU: Intel Atom Processor N2800/N2600 Series
Graphics: Intel GMA 3650

I could assume that indeed, https://wiki.archlinux.org/index.php/Intel_GMA3600 would be the proper driver for me.
However, based on information from the website, the kernel version - 3.17.2, and the xorg version - 1.16, I am quite worried if I can try to install these drivers.

Are there any newer versions/similar drivers available?

It seems you may need to compile it from git as described there, or use mode-setting. I've been pleasantly surprised by how well the mode-setting driver can work. Unless you have very particular needs (intense graphic processing, or want more FPS from a game than the human eye can perceive) then mode-setting should work well. The xf86-video-intel driver is rightly ignored by X and as vesa is the only fallback you have installed, it uses that ... and vesa can really suck.

I'd suggest using xf86-video-modesetting, and only if you do have some very particular needs that it doesn't satisfy, try building from git as described in the wiki.

kdiablo · 2014-11-06 21:20:13

I tried xf86-video-modesetting - and it works perfectly!

I followed the short description on https://wiki.archlinux.org/index.php/In … org_driver

Arch Linux rules, both Xorg and KDE work without any problems.
karol & Trilby, thank you very much for your help!
