How do I make Mint 9 LXDE monitor refresh rate stick?
I just installed Mint 9 LXDE on an old computer, and after working around the 'impossible to log in' bug (that I also encountered on the Fluxbox version of Mint 9), I've got it running nicely except for one thing:
The system automatically sets the monitor refresh rate to 85 Hz, but the monitor doesn't handle that well - it makes the screen image wobbly - and it should be set at 75 Hz. I keep setting it to 75 Hz in Preferences->Monitor Settings, but after rebooting it's back at 85 Hz again.
Is there some way to make the 75 Hz setting stick?
(I googled for a solution but everything I found refers to config files that aren't on my system, eg. xorg.conf, so I'm guessing that Mint 9 LXDE is doing things differently.)
Thanks.
