[WARNING] 302.17 doesn't accept modelines 295.53 and older did just fine
Title might sound more dramatic than it really is. After upgrading to 302.17, I was greeted with login screen on low resolution and refresh rate.
In Xorg.0.log there's information like:
[ 1350.735] (WW) NVIDIA(0): Error while parsing panning domain in mode description
[ 1350.735] (WW) NVIDIA(0): "1152x864@120"
Not only I'm using modes like this for ages, ALL the modeline calculators on the Internet produce modes with "@" followed by refresh rate.
Now every ModeLine containing "@" is rejected.
Work around was to replace every "@" with "_" in xorg.conf and all looks working.
I hope this helps someone :)
