So from DrakeConf I tried to change it to 800 x 600, and something terrible happened: the screen keeps blinking all the time and it won't start XWindows, it stays in the login screen (text mode)and it's almost impossible to type anything unless I do it very, very slowly and making sure I type each letter just in the exact moment that it blinks, which is every 2 seconds approx. I've tried a new install of LM 7.0 (Air), but it hangs after it gets to the second stage install. Is there a command or a way that I can get back into de screen configuration again and change it back to where it was?(although its gonna be very difficult to type, but I don't mind trying) Or, Is it better to download (with W98) LM 7.1 and install it over the old one? I've also tried to boot with the boot disk but no way, it doesn't work, I guess I didn't make it correctly. If someone could help me it would be really great. My pc is: Pentium 133mhz 2 hard drives (one with W98 and the other LM 7.0 (Air)-kernel 2.2.14-15) 24M of RAM CD-ROM OTI-Hermes 10x Monitor: Olivetti DSM 28-142 PS / LOW EMISSION Graphic Card (or whatever it's called): S3 Trio64V+ PCI(765) In Linux Mandrake list of Monitors the olivetti doen's show, so it was set as Generic SuperVga something (I don't remember the rest) Another thing: I tried with another old Compaq Monitor I have lying around unused, but exactly the same problem. TIA Carol^ P.S.: I was so happy with my Linux working, included the internet connection. I don't why I had to fiddle with the screen resolution, it wasn't so terrible. Now I don't know what to do!!!!!!! >> well you did what i did once for some reason the refresh rate is not configured properly the only way to fix it is to use the "xf86config" program i dont know why they named it the same as the file it creates but ohwell, the other way you might be able to do it is load linux in single user mode i believe you could also use failsafe in the grub menu it should work, at the command prompt log in as root, type "login" just in case you havent loged in like this my comp loads x at start up here you will have something like [$root@ /root] something like that i dont remember basically it says your loged as root and your current location, type "xf86config" and you will have to select mouse keyboard, monitor and graphics card MAKE SURE you use the factory defaults in your selections anotherwords match the specs of your monitor and graphics card! OPTION #2 same as before but you are going to do some browsing instead of using xf86config, your going to type cd /etc/x11/ you may have to do some "ls" what your looking for is something like xf86config.old, your x11 folder may have more to the name like x11f86, unfortunately you cant use console which color codes your text so you can be sure your opening a folder some things are just named wierd, you could try a text editor to help you such as vim or emac have fun!
