Public bug reported:
Hello,
I'm using Linux Mint 14 MATE, 3.5.0-23 x64 with a NVIDIA GeForce GTX 460 video
card and a ViewSonic VG1921wm monitor.
Using the NVIDIA privative driver I can set the monitor resolution to 1440x900
@ 75Hz in Menu Preferences Monitors. Then with the monitor buttons I look
in Information and it says that vertical frecuency is 74.8Hz, and when I set it
to 1440x900 @ 60Hz, the monitor says that vertical frecuency is 59.9Hz, namely:
all works well.
But when I'm using Nouveau it has no effect, wathever I set in Menu
Preferences Monitors (as user or as root, is the same) the information
of my monitor always shows a vertical frecuency of 59.9Hz.
My graphical system is crashing with some applications at fullscreen
using Nouveau finally showing a your x-system is bad configured (or
something like that) message, nevertheless I haven't configured anything
else than the refresh rate in Menu Preferences Monitors since I
installed Linux Mint, I don't know if it may be related.
I've already reported this problem in the Linux Mint forum and they've
linked me here. The thread is
http://forums.linuxmint.com/viewtopic.php?f=59t=125253 if your want to
take a look.
1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -
About Ubuntu
*** Linux Mint 14 Nadia
2) The version of the package you are using, via 'apt-cache policy
pkgname' or by checking in Software Center
*** I don't know if it's a concrete package bug or the nouveau driver is
releated to the kernel... I'm not sure which package is failing.
3) What you expected to happen
*** Vertical frecuency showed by my monitor should me the same is selected in
Menu Preferences Monitors
4) What happened instead
*** My monitor always shows 60 Hz as vertical refresh although I select
75 Hz in Linux Mint
What can I do in order to get the real 1440x900@75Hz resolution with
Nouveau?
