When GDM is started resolution is about 1600 and refresh rate is ~60
When I login to Gnome it's normal 1280x1024 at refresh rate 85
What I do wrong?

You probably have defined higher resolutions in your Xorg configuration and set them manually to a lower resolution in Gnome. The solution is to reconfigure your configuration. Edit as root the following file /etc/X11/xorg.conf
Find the section called "Screen", there you will find lines looking like this:
SubSection "Display"
Viewport 0 0
Depth 24
Modes "1280x1024" "1024x768"
EndSubSection
In the "Modes" line remove all settings that are higher than you desired resolution. After that restart you X-Server by pressing ALT+CTRL+BACKSPACE.

I'm having the same problem. But the xorg.conf fix didn't fix it.

I was having similar but different problem.
Sometimes, after some of the application's crash I had to restart xorg (ctrl-alt-backspace) and screen was switching to weird resolution (perhaps, 320x200 or similar) in gdm and, after login, in gnome, too. The only way I could get my proper resolution back was to reboot.
I didn't see it for couple of months now, but it would be interesting to know what it might have been

I had a similar issue which may or may not be exactly the same. I simply used xrandr to fix it.
