This only works if you own a copy of the Quake3 CD. If you have a mirror for it, please let me know.
I have not been able to get the demo to work in Linux (Except using the Windows demo through Wine).
If you've tried to download the Quake3 installer from idsoftware's site, you've figured out it won't work in Ubuntu 7.10 x86_64.
I even went to getrpm and got the Fedora Core version (launched, but gave the error "user interface is 3 expected 6). Like usual, I was trying too hard...
For some awesome reason, Ubuntu puts Quake3 in its repositories (might have to turn on non-free, or restricted with Synaptic).
Open a terminal and type:
sudo apt-get install quake3-data
It will prompt you for the Quake3 CD. Pop it in your drive and go to work. I'm pretty sure the Windows install CD will work, just provide the quake3 folder location.
It will then download the stuff it needs from idsoftware site (20+ minutes).
Then it will drop you back at a shell. You want to type:
sudo sh /root/linuxq3apoint-1.32b-3.x86.runAMD64 users, type this instead:
sudo linux32 sh /root/linuxq3apoint-1.32b-3.x86.runThen launch the game by typing this at console:
If you get:
Sys_Error: Couldn't load default.cfgThen type this:
quake3 +set fs_basepath /usr/share/games/quake3
