Hi everyone, I have a problem with my screen resolution in Linux. This happens with both openSUSE 11.4 and Fedora 15. The moment my PC restarts after I have installed the operating system it will boot up with a screen resolution higher than my monitor supports. My screen supports a maximum resolution of 1600 x 1200 @ 75Hz and Linux sets the default resolution way too high at boot, now all I get is a message from my screen asking me very nicely to change the signal timings, but I can’t because I can’t see anything to change it to a lower value (I don’t want it so high anyways because then everything is too **** small). My monitor is a SONY GDM-5410 and the Graphics card is an AMD Radeon HD 4870 1GB. It nly works when I boot the system to FailSafe mode, but then I can’t cahnge it permanently. Any ideas?

Could you tell us which desktop and which video driver you are using? And
please tell us anything else you might know to help us understand your
problem, after all none of are likely to be able to sit at your computer
and fiddle and watch the boot messages (see bootlog). Do you have
autologin setup?
Also, if you have grub in the boot sequence you can try failsafe mode or
add " 3 " to the existing initialization string and get a (probably 80 by
24) console session.
