Output from Xorg.0.log
On my Lenovo Thinkpad Edge E330 (i3 3110M, HD4000), since upgrading to Mint 16, I got multiple issues with screen rendering:
* glitches/corruption mainly in Firefox and Thunderbird (random small black blocks in the browser window, of about 10x4 pixels, or corrupted text when scrolling)
* Various games that did run fine in Mint 15 using Wine/Playonlinux now give troubles:
DeusEx refuses to use high-res textures form NewVision even when using OpenGL renderer and correct settings, Sword of the Stars: The Pit (I know, there's a native version, but I don't own that) refuses to start at all and complains that it could not find a Direct3D device that supports XNA framework reach profile - both of which worked fine under Mint 15.
Icewind Dale is unplayable fullscreen in OpenGL mode, since the picture flickers like crazy - windowed works fine.
I doubt that it's a Wine issue, since I made sure to use the same version and settings as before.
* Shadowrun Returns (native Linux version) produces glitches on overlays in the form of, for lack of better words, an array of small boxes/rectangles and lines that appears and quickly vanishes again, sometimes flickering on and off for a short time.
I installed the xorg-edgers ppa and updated, which seems to have affected the glitches in Firefox - I now don't get the small boxes on scrolling anymore, but rather the bottom right part of the screen is diagonally filled with an array of small coloured boxes for a fraction of a second, which just shows up and vanishes again randomly from time to time.
Sorry that I can only offer this somewhat vague description, it happens too fast to capture it on a photo or screenshot...
As for my specs:
Mint 16 Cinnamon 64bit
Mesa version: 10.0.0-0ubuntu0sarvatt3 from edgers ppa
Kernel: 3.11.0-12-generic x86_64 (64 bit)
Here's the output from inxi -Gxx:
Card: Intel 3rd Gen Core processor Graphics Controller bus-ID: 00:02.0
X.Org: 184.108.40.2061 drivers: intel (unloaded: fbdev,vesa)
GLX Renderer: Mesa DRI Intel Ivybridge Mobile GLX Version: 3.0 Mesa 10.0.0 Direct Rendering: Yes
To specify - I did a fresh install of Mint 16, no distro upgrade.
Are you using SNA for 2D acceleration?
Yes - but I think I had tried setting it to UXA, without success.
To be sure, I'll try again tonight and report back!
Ok, I tried to switch to UXA again, both by adding
and by creating
Identifier "Intel Graphics"
Option "AccelMethod" "uxa"
into the respective files. Neither seems to have changed anything. Since I'm a noob with that stuff, is there a way to check whether I'm currently using SNA or UXA?
Ok, forget that, I have checked /var/Xorg.0.log
with the "uxa" option, I find only uxa in the log, with "sna" only sna, so I guess I had switched to uxa.
Anyway, it did not change anything about my issues.
I have downgraded mesa and xserver again, since xorg-edgers had introduced another bug I couldn't get rid of otherwise.
