When I start graphic mode in the dialog after booting, text mode appears. Has this something to do with my graphic card (S3Trio 2MB)? I have only 32 MB RAM in my PC.

I'll assume X is installed. You need to run xf86config to setup your /etc/XF86Config file. Be sure to select S3 Trio from the card list. Then type startx. I have a P100 with 32Mb RAM and an S3 Trio card. It runs X just fine.

Stefan, from your subject, it sounds like you don't have the installation complete. in that case, editing your /etc/XFConfig isn't possible, because it hasn't been created yet. i presume you created a linux installation boot diskette using rawrite, and are doing your linux installation from cd-rom. is this correct? i had a devil of a time getting linux installed on my box, in part because of my video card. i was using a Diamond Stealth III x540 Xtreme 32Mb AGP2x card. That card is based off the Savage 4 chipset. Red Hat's graphical install didn't like my video chipset. It didn't refresh the screen properly when scrolling in a dialog box or jumping to the next step. Soon the whole screen was a smeared black mess. Is this what you're experiencing? The problem I'm describing is documented; I wish i still had the URL. I think the page I read describing it was on http://linuxdoc.org somewhere. (A good site to visit anyway, for any linux user.) I bought a new video card. I probably could have completed my installation in text mode... text mode isn't any more difficult, once you get used to tabbing and arrowing instead of mousing. In my case, it was time for an upgrade anyway. The RH 7.0 installer had no trouble recognizing my new NVIDIA Geforce DDR chipset. Also, another snag I had to overcome was an Anaconda Dump. I was doing a dual-OS installation (W98SE and RH 7.0). The installer didn't like being asked to mount my msdos hard drive partitions during installation, and it would bomb out while setting up the filesystem. I had to go back and specify only the linux native and linux swap partitions during the disk druid step, and then manually mount my msdos partitions after i was up and running. once i understood the problem, it was no longer a problem at all. a howto and a man page on the mount command, a quick text editing session, and i was accessing my old media library in no time.

I also had a problem installing X on my system. Mine was an old system with a trident 9000i card. Was unable to get drivers for this. My advise is that if you have old systems, don't even try installing redhat.
