Re: Fonts in Firefox "crumble" (Mint 16 Mate RC)

Postby koala on Mon Dec 16, 2013 9:01 am

The reason for this problem is related to "Acceleration methode" used by Intel driver (xf86-video-intel):

- The old methode is UXA - (Unified Acceleration Architecture)
- The new methode is SNA - (Sandybridge's New Acceleration)

SNA is used by default, as to august 2013, in the Intel driver (from version 2.21.14-1).


To solve the problem, we need to use the old UXA acceleration methode.
We need to create a file named 20-intel.conf , with the following content:

Code: Select all
Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod"  "uxa"
EndSection



Put this file (20-intel.conf) in /etc/X11/xorg.conf.d/
If there's not a folder named xorg.conf.d, then create it!


Reboot and enjoy... no artifacts there!

I applied koala's fix and in a quick test it's working great, no glitch in sight.

Thanks, koala, that was awesome.

For anyone doing this, my display configuration reset after the change, so I had to reconfigure dual monitors, resolution, etc., but everything is looking great so far.

Hello all,

All the credits are for the "arch world people".
I use Manjaro Linux & Linux Mint (on two systems), and i read about this problem somewhere in a arch forum. I don't remember exactly where.

I applied Koala's fix at my home computer; it worked.
On the other hand, I did nothing at my work computer but the problem is gone there too. It must be something came with the updates. Does anybody still have the problem without Koala's fix?

Put this file (20-intel.conf) in /etc/X11/xorg.conf.d/


Hi Koala,
Please be more specific ...where is the folder location.
Thank you in advance

By complete chance, I happened to learn about UXA and SNA on completely different hardware (dell D610, which wouldn't start the X server without my hand-built Xorg.conf and a custom-compiled kernel 3.13.5) , while trying to fix sync-to-vblank problems on a dell laptop. Good to see my Xorg.conf will be useful on my G550, too :D

The G550 is a kind of loud and underpowered laptop, but I still love it for how rock solid it is (Mine has about half of its case screws missing and is using a fan from a G450 which doesn't fit inside without punching holes in the plastic, but it still works just fine :D). Glad to see that I won't have to use Mint 14/Ubuntu 12.10 forever.
