A short (and incomplete) HowTo on updating LMCE (1.1 Beta2) to the latest display drivers.
I'm writing these from memory more or less so it probably needs to be tested and updated, don't be shy.
1. Go to a console (text) terminal by holding [CTRL]-[ALT] and pressing the [F1] key simultaneously, log in with the user account you have created during the Kubuntu install and become root, if you haven't done so already.
<you>@dcerouter:~$ sudo -s
2. Prepare the system for building the driver packages, this only has to be done once, please add if you needed more.
root@dcerouter:~# apt-get install dpkg-dev debhelper
3. Download the latest linux drivers from AMD/ATI (version 8.38.6 currently), if you haven't done so already.
root@dcerouter:~# wget https://a248.e.akamai.net/f/674/9206/0/www2.ati.com/drivers/linux/ati-driver-installer-8.38.6-x86.x86_64.run
4. Build installable packages for Feisty.
root@dcerouter:~# sh ati-driver-installer-8.38.6-x86.x86_64.run --buildpkg Ubuntu/feisty
5. Install them (maybe the order needs to be changed).
root@dcerouter:~# dpkg -i xorg-driver-fglrx_*_i386.deb xorg-driver-fglrx-dev_*_i386.deb fglrx-kernel-source_*_i386.deb fglrx-amdcccle_*_i386.deb
6. Now it needs to be configured. There are a lot of ways to do that.
(ToDo: Write some real instructions, with a bare full config example)
One way is to edit the "/etc/X11/xorg.conf" file by hand and change at least
Section "Device" Identifier "Generic Video Card" # or whatever Device was specified in the "Screen" Section Driver "vesa" # or "ati" or "radeon" or something. ... EndSection
Section "Device" Identifier "Generic Video Card" # <- leave this line as it was, unchanged! Driver "fglrx" # <- change this one ... EndSection
You might want to make a backup copy of this file once it works since it seems to be overwritten rather eagerly, and not always by the most adequate of tools.
Here's a quick and crude way to upate the configuration, it simply changes "vesa" to "glfrx" (not really recommended, better to do it properly).
root@dcerouter:~# sed -e '/[^#]*Driver/s/"vesa"/"glfrx"/' -i /etc/X11/xorg.conf
There might be other options that perhaps need to be changed depending on your existing configuration file, feel free to add them here.
You can test whether it works with the command "startx", there should be an ATI controll center installed now if you followed the previous install instructions, this could be for your futher configuration needs YMMV. Make a backup copy of your /etc/X11/xorg.conf when everyting works properly and reboot.
Coming soon to a browser near you!
X-windows won't start anymore at all
Reboot into safemode (hit [Esc] when Grub tells you to) and restore a working copy of your /etc/X11/xorg.conf, or edit it by hand to fix the problem. Test it with the command "X" and press [CTRL]-[ALT]-[Backspace] simultaneous to quit, then reboot when it works and you're done.
