xorg.conf

[Teunis]

Just an observation, today I saw an update for the nVidia driver and a little later it had disabled the xorg.conf file by appending the date (in American) to it's name.

I think the nvidia-prime package is responsible for this?

Edit: Yup... removing nvidia-prime (and bbswitch-dkms) finally let me have my monitors in the correct, xorg.conf-defined order. I don't know why this got installed automatically on a non-Optimus system...

On my system, that file was created but as a backup. The xorg.conf file is still there but with changes commented. It removed the keyboard and mouse sections/line because HAL now detects and controls those devices. Keyboard settings are now read from /etc/default/console-setup.

[Teunis]

Aha, I hadn't heard/read about /etc/default/console-setup but on my computer it has no input for the screen brightness.
That's how I found out there was something wrong, I couldn't change the brightness.

The same thing happened to my /etc/X11/xorg.conf file, which I had created to switch from "sna" to "uxa" acceleration, which stabilizes the accelerated video.

Hm. Version 331.49? My system updated to that recently. My hand-crafted xorg.conf remained untouched.

Hm, those are Intel-related options, not nVidia. UXA is pre-Sandy Bridge. Are there still problems with SNA?

Hey, welcome back! (Till the Vega Interop!)

Yes. You're right, Intel is my video chip and is the one I use, but I also have a secondary GT 650M Nvidia chip in this Acer and the xserver upgrade apparently saw and de-activated my hand-crafted xorg.conf file twice, in two successive updates, by appending the date after it.

SNA acceleration improves my acceleration by about 10-20% (guesstimate) but also creates tearing and black triangles and rectangles, along with ring hangs. When I create /etc/X11/xorg.conf with

Section "Device"
   Identifier  "Intel Graphics"
   Driver      "intel"
   Option      "AccelMethod"  "uxa"
EndSection

my accelerated graphics is stable, and I still get a vsync speed of 60fps in apps like Stellarium and Minecraft.

What versions of xserver-xorg-core and xserver-xorg-video-intel do you have installed?

[GreyGeek]

What versions of xserver-xorg-core and xserver-xorg-video-intel do you have installed?

xserver-xorg-core: 2:1.15.0-1ubuntu7
xserver-xorg-video-intell: 2:2.99.910-0ubuntu1

[SteveRiley]

Those are quite fresh versions. Maybe it's your hardware? How old is the machine exhibiting the weird artifacts? Which Intel graphics generation?

[Teunis]

About the nVidia version on my W520, it's 331.38

[SteveRiley]

These nVidia problems are odd. I wonder why mine didn't get overwritten? I'm using Xorg-Edgers, which has 331.49.

Mine was not either. It made a copy as others have had - with the date appended to the file name - but left the original intact except for the removal of keyboard and mouse stanzas.

[SteveRiley]

I'm stumped. Nothing has happened inside my /etc/X11 since last year:

I'm happy...I think? LOL

Oh, and I'm indifferent...
