Upgrade to xf86-video-intel causes screen to be unreadable

I just upgraded to xf86-video-intel and the screen went all wonky.  Thunar, terminal, pamac all displayed correctly until you typed or moused over file.
Downgraded back to previous version and all is well.
Just thought you might like to know.
Nothing on the Arch News site.

Re: Upgrade to xf86-video-intel causes screen to be unreadable

Did you try changing the "AccelMethod"?

Try "uxa" or "glamor" instead of "sna"

See intel(4) & xorg.conf(5)

Re: Upgrade to xf86-video-intel causes screen to be unreadable

I forgot about that.  However when I looked to see what it was, I found that

/etc/X11/xorg.conf.d/20-intel.conf

does not exist on my system.

For now, I am satisfied with the downgrade.  Perhaps sometime later I will try the upgrade with a 20-intel.conf file setup.

Re: Upgrade to xf86-video-intel causes screen to be unreadable

I had that itchy feeling to go ahead and ... 
I added the /etc/X11/xorg.conf.d/20-intel.conf file with AccelMethod as   uxa
Logged off and everything was fine.
I then changed it to   sna
Logged off and video was a mess.
Opened a terminal and changed it back to    uxa.
All is well.

Re: Upgrade to xf86-video-intel causes screen to be unreadable

This should fix it.
Create /etc/X11/xorg.conf.d/20-intel.conf
Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod"  "uxa"
EndSection

Seems that Intel uses the   sna   AccelMethod by default and by using uxa it fixed mine.
I did not have that file so I am just assuming Intel uses   sna by default because when I set it to   sna  video goes bonkers.

Oops, thought I was on Antergos' forum.   They had a similar problem.

Re: Upgrade to xf86-video-intel causes screen to be unreadable

This was in my pamac history

Upgraded xf86-video-intel (2.99.917-5 -> 1:2.99.917+364+gb24e758-1)

the xf86-video-intel (2.99.917-4 is the one that worked for me until I added/changed the 20-intel.conf file.

Re: Upgrade to xf86-video-intel causes screen to be unreadable

I had a similar issue, but kodi kept crashing.  So I opened it in a terminal and when it crashed, it said that it was the xorg server.
I had the testing driver, which had been working fine up until a few days ago.  I blacklisted the testing version and installed the aur version, and kodi has stopped crashing.  I may have to try this and see though.

Re: Upgrade to xf86-video-intel causes screen to be unreadable

It didn't fix it.  When I restarted, thanks to a short power outage, before starting x I removed the ignore and did the install of the testing package, and used the script that you posted.  With kodi on my one page, and then opening up urxvt, everything slowed down, to the point of insanity.  Yet there was no extra load on the machine.

So I went back to the extra package, and had the same issue, so removed the 20-intel.conf file and things are working fine now.

Not trying to hijack, just letting you know.

Well I am glad that it worked out for you as I know it can be a real drag having messed up video.

Re: Upgrade to xf86-video-intel causes screen to be unreadable

But as far as I know the Intel driver uses SNA as default for quite a while now.
So this sounds more like a regression bug in the latest version to me.

I'm experiencing similar problems running a Intel Core i7 3667U with an Intel HD Graphics 4000.

Re: Upgrade to xf86-video-intel causes screen to be unreadable

Yes, this is a regression. Switching to UXA is *not* a fix, it's a temporary workaround. It's not a fix because SNA remains broken. And the only way it'll get fixed is if someone who experiences this regression makes a bug report upstream (bugs.freedesktop.org)! They can't fix things if they don't know something's broken. BTW, no issues here on a HD4600.

Re: Upgrade to xf86-video-intel causes screen to be unreadable

Sure, this would have been my next step.
Anyway, there is already a bug report open: https://bugs.freedesktop.org/show_bug.cgi?id=91105

Re: Upgrade to xf86-video-intel causes screen to be unreadable

It's not relevant to the thread, but I'm afraid the Intel driver issue is bigger than that:

I also want to supplement the driver issues. X completely broke for me when trying to do full screen with mpv. I've never had x crash before but I could reproduce it crashing easily. Just fullscreen a video with mpv and there would be heavily vertical interlacing and eventually video playback would stop.

I downgraded mesa at first and it partially fixed the problems, but downgrading xf86-video-intel has (so far) solved everything.
