Re: distorted graphics

I was having this problem on a laptop. I filed a bugzilla report.
https://bugzilla.redhat.com/show_bug.cgi?id=1226743

The feedback I got on that is that it was a change in the kernel that caused this to manifest. The solution seems to be (quoting comment 7) "disable WC mmaps until userspace issues are sorted out."

I did not see this thread first or I would have tried the solution posted here. The kernel fix also works, but not quite perfectly. I have seen some graphics in Firefox distort, but they corrected on refresh.

Anway, if anybody is having this problem on an installed system, please try out below steps :

Create a new file called /etc/X11/xorg.conf.d/20-intel.conf with below text:

Code:
Section "Device"
        Identifier  "card0"
        Driver      "intel"
        Option      "AccelMethod"  "uxa"
EndSection
Reboot and see if it resolves your issue. I am not sure whether this can be done on a live dvd. But you can try coz if the live dvd is running from a pen drive, there is some storage space available on it.
On the parts with the quotations, do we put the device, card, and all of the other stuff from our PC/Laptop?

Like say, for example, I have a Lenovo G550. Where it says
Code:
Section "Device"
Do I put v
Code:
Section "Lenovo G550"
?

Re: distorted graphics

No, you put it in exactly the way it is shown.

Code:
Section "Device"
        Identifier  "card0"
        Driver      "intel"
        Option      "AccelMethod"  "uxa"
EndSection
Easiest way is to create the file in your favorite text editor, and just do a copy/paste then save it. Don't change anything, The file contents should be exactly as shown.

Re: distorted graphics

Hey I'm back wondering if you can talk me through the kernal update (4.05) and removing the file I created to permanently fix this issue?

On Fedora mag it says update and then install the new kernal but is vague about removing the original workaround file - when to do this (ie before or after kernal update) and how to do this exactly.

That'll have to be two beers then.

Geoff.

Thank you so much Bhardwaj. Signed up just to thank you. You've saved me and several others a lot of time and helped avoid frustrations.

If you could, please elaborate what has changed by adding this file and configuration.

Well, glad it worked out for you well. I think with latest kernels, you won't need this fix anyway so try fully updating your system and see if you can work without this fix.

This fix basically asks the intel graphics driver to use the UXA architecture instead of the newer SNA architecture for graphics acceleration. Although SNA is designed to be backward compatible, the combination of certain kernel and intel driver version was causing this issue. Using the older acceleration method was working fine. Both Intel driver team and kernel developers have worked on this and it's been resolved now.

In a Linux command shell box, type:

su -
(key in your password)

yumex --root

The newest kernels all start with the filename 'kernel', so place a checkbox on everything with 'kernel' in it.

After it's finished updating, yumex will update the list of software updates left. You can continue to update your software or just close down yumex and you'll be put back into the command prompt.

Re: distorted graphics

Indeed, the issue was patched. It would be better to download and use a respun ISO from this resource. They were last updated 10th October 2015.
