i went and saved the client, but when i try and drag it over to command line to run i get this:

[root@localhost iamsam]# /home/iamsam/Desktop/doom3-linux-1.3.1302.x86.run
bash: /home/iamsam/Desktop/doom3-linux-1.3.1302.x86.run: Permission denied

and i am pretty new to linux, and i am brand new to linux gaming, so i might just be making a stupid mistake, but idk what that would be, so any help would be appreciated

chmod 777 /home/iamsam/Desktop/doom3-linux-1.3.1302.x86.run

yeah i tried making it an executable right after i posted, then i installed everything, and got all excited, but then i got this error:

[iamsam@localhost ~]$ doom3

im running FC5, and the machine specs are, amd64 3200+, 1gb ram, and 256mb nvidia 6600, just in case you need to know

Yeah, it segfaults on my amd64 3200 too, so it's not just you. Haven't figured out why yet.

(Can't remember offhand exactly what version I'm using.)
