I'm trying to install xorg-server in debian wheezy.

I tried to execute a simple command

apt-get install xserver-xorg

It attempts to install ton of video drivers and dri-modules: for nvidia, for intel, for amd, for vesa and so on. And I'd like to keep the system image as small as possible.

How to tell debian that I need the only video driver supporting the card that is present now.

By default, xserver-xorg pulls in xserver-xorg-video-all, which pulls in all the video drivers.

If you know which driver is appropriate, you can install it along with xserver-xorg, and it will satisfy the alternative dependency on xorg-driver-video, avoiding the xserver-xorg-video-all dependency altogether; thus for an Intel IGP:

apt-get install xserver-xorg xserver-xorg-video-intel

If you want to make doubly sure that xserver-xorg-video-all isn't installed, you can use something like

apt-get install xserver-xorg xserver-xorg-video-intel xserver-xorg-video-all_

(note the underscore, which instructs apt-get to purge the package).

To avoid installing the libdrm* packages, you need to avoid libgl1-mesa-dri which depends on all of them (with no easy workaround, so if you want DRI support you need all three implementations, unless you use equivs — but they're quite small). xserver-xorg recommends the package, so

apt-get --no-install-recommends install xserver-xorg ...

should do the trick. This is a good idea anyway if you're after a small image.

  • Stephen, +1, what about the _ trick? Is this just to match nothing when doing Regex match? – heemayl Oct 16 '16 at 22:40

    @heemayl it tells apt-get to purge the package (+, - and _ suffixes are equivalent to install, remove and purge respectively, regardless of the command given to apt-get). – Stephen Kitt Oct 16 '16 at 23:00
