How sparse can you get your xorg.conf?

how small can you get your xorg.conf with everything working for your system? (without being blank)

        Device         "v0"
        Monitor         "m0"
        DefaultDepth 24
EndSection

Things i had to set manually;

1) Keyboard layout, because it defaults to US
2) Two mouse keys don't work had to manually set, Emulate3Buttons defaults on (wanted it off)
3) "VideoOverlay" is off by default (or is not auto detected)
3) needed to set DPI to 96
4) needed to set color to 24 (defaulted to 8?)

apart from that, the auto detection is vastly improving IMO.

The main premise behind this, is to debate the auto detection capabilities of hardware by xorg.

a nonexistent one works well too.

Some settings aren't, or cannot be reasonably autodetected; for example the size of the virtual framebuffer when using mergedfb (you need to specify Virtual 2048x2048, or more:)

Same thing with:

Look at xorg log and you'd know what are the defaults, so you can clear out those entries.

This was generated first by nvidia-xconfig, then by nvidia-settings (for the second monitor). I added two lines and edited two lines only. I know for a fact that I could remove all mouse and keyboard stuff, but I don't care enough to do it:

--EDIT--

I did it anyway!

were can i get info on ATI(fglrx) tweaks in xorg.conf? all i want is the faster 2d and 3d
performance, but not bothered about compriz.
BTW, my hardware relation to the first post (for reference)

+1 , I would really like to know this aswell, since I'm getting hardlocks with fglrx...

I played that game too a while ago.
With no config at all, I had a problem that it wouldn't detect the fonts.
So I added the Files section.
Then the intel driver has performance problems by default, so I added some options to the Device section.

Section "Files"
    RgbPath      "/usr/share/X11/rgb"
    ModulePath   "/usr/lib/xorg/modules"
    FontPath     "/usr/share/fonts/misc"
    FontPath     "/usr/share/fonts/100dpi:unscaled"
    FontPath     "/usr/share/fonts/75dpi:unscaled"
    FontPath     "/usr/share/fonts/TTF"
    FontPath     "/usr/share/fonts/Type1"
    FontPath     "/usr/share/fonts/local"
EndSection

Section "Device"
    Identifier  "Card0"
    Driver      "intel"
    Option       "MigrationHeuristic" "greedy"
    #Option      "AccelMethod"   "exa"
    #Option      "XAANoOffscreenPixmaps" "true"
EndSection

I have been using that config for a while without any problems.
Well, I cheat a bit though, since I am using a custom keyboard layout outside of the config, using xmodmap : xmodmap ~/.Xmodmap

DonVla · 2008-03-10 15:18:30

is the fontpath entry needed no more?

if i add them all manually i get a arch icon mouse cursor, so it seems not all or auto detected.
although i never know properly what "i" should add,

Not if every apps you use supports fontconfig, which is not my case. Some developers consider freetype/fontconfig/Xft to be bloated and don't use them in their apps.
In that case, you need correct fontpath entries.

If drivers were decent, I don't think that any tweaks would change much, though you might loose some stability.

Last I checked (I currently use xf86-video-ati), fglrx (now catalyst?) had an aticonfig utility for setting a bunch of stuff. Maybe they even have a gui control panel?

the list of files in catalyst-utils should give you some ideas:

pacman -Ql catalyst-utils

Cerebral · 2008-03-10 19:30:27

GUI control panel is amdcccle
aticonfig still exists for command-line configuration tho

gav616 · 2008-03-10 20:20:53

i looked at http://forum.compiz-fusion.org/showthread.php?t=6794
most are for compiz, but enabled by default anyway i.e. AIGLX, DRI, Composite (by checking xorg.log most are enable anyway)

its just my 2d performance is just completely crap, hate ati, although i might try Textured2D and such, its meant to be faster then videooverlay option? ... :S

Note 0:
The 2 old Video options (VideoOverlay and OpenGLOverlay) are from now on deprecated. Catalyst 8.3 driver brought us the new XV Textured Video without diagonial tearing problem and uses the 3D engine to accelerate video with the best video results ever since!
But remember to specify the 2 old options at xorg.conf to be off, cause amdpcsdb doesn't forget your mistakes that easy! So just removal is not enough...
Note 1:
Textured2D option utilizes a new 2D acceleration mechanism of the driver which really boosts up 2D performance and behaviour! It also loads GLESX module. (I have seen a 9550 old Radeon easily overcome at 2D performance my X1250 with this option!)
Important when works cause it improves the slow windowed scrolling problem every ATI user faces when use Compiz-Fusion with AIGLX and fglrx driver. BE CAREFUL with that! It is a hidden option and it may NOT work with all ATI cards! If you cannot connect to X server or face strange colours just commend it out at xorg.conf or set it to "off" But Try it! Really worths checking! Now it works for IGPs too, from 8.2 and on driver (Works for my X1250!) At 8.3 driver this is working even better!

hmmmmmmmmmmm..

my xorg.conf is really sparse: between each actual config line I have a thousand lines each containing 80 ascii space characters. It's a pain in the arse to edit, but the bzip compression on it is amazing!

neotuli · 2008-03-19 04:33:04

Actually I was rather impressed by xorg's autodetection recently. The fact that you can make Xorg do the work makes livecd scenarios a whole lot easier than they used to be.

Oh and uh...

$ wc -l /etc/X11/xorg.conf 
101 /etc/X11/xorg.conf

shining · 2008-03-19 10:36:32

After the new xorg-server, my two different minimal xorg.conf on laptop and desktop made Xorg segfault.
So I had to revert to a more standard config on both (generated with Xorg -configure) and it works fine.
