xrandr maximum resolution is well below the preferred
My monitor has a preferred resolution of 1440x900 (A number located by booting to Puppy which displays correctly). I have use Ubuntu, Debian, and Mint with this computer and they have all been fine with the resolution. But withg CentOS 32b on a Dell Latitude D620 when I go to xrandr it outputs this:
Code:
[~]$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 800 x 600, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
1024x768 61.0*
800x600 61.0
I did some reaserch and I found that I should add a new mode so I did what they said and got this:
I then tried to find out how to fix this "gamma" issue and found several solutions, none of which worked. Does anyone have any idea how I could get this working?
Also, from what I can tell it's using Intel integrated graphics.
I didn't know what to put for my laptop's monitor information so I just made it up based on my laptop information assuming it wasn't important.
I restarted X11 and my resolut is still off, althrough now xrandr outputs this:
Code:
[~]$ xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 640 x 480, current 1024 x 768, maximum 1024 x 768
default connected 1024x768+0+0 0mm x 0mm
1024x768 76.0*
800x600 73.0
640x480 73.0
A frequent problem is that the HorizSync and VirtRefresh are too low. As long as you are using a LCD style monitor make the upper bounds something like 120.
You should be able to find your desired resolution in your Xorg.x.log file (though it might be rejected as being "xxx out of bounds", where xxx indicates one of horizontal sync or vertical refresh). I usually just up the HorizSync/VirtRefresh values until it works.
LCD monitors are not damaged by things out of bounds (CRT monitors can blow the flyback transformer, so don't do it on those).
I removed the line to no avail and there is no "out of bounds" message, but I did look for errors in that file and found this:
Code:
[ 96.721] (EE) open /dev/fb0: No such device
[ 98.380] (EE) PreInit returned 8 for "HDA Intel Headphone"
[ 98.380] (EE) config/hal: NewInputDeviceRequest failed (8)
