Incorrect screen size in F17

LDPDC · #1 8th July 2012, 12:56 PM

After upgrading from F16 to F17 the beefy miracle was so beefy it decided that my prefered screen size would be 2048x1536 and max to 8192x8192.

Code:

xrandr

Answer:

Code:

Screen 0: minimum 320 x 200, current 2048 x 1536, maximum 8192 x 8192
LVDS-1 connected 2048x1536+0+0 (normal left inverted right x axis y axis) 0mm x 0mm panning 2048x1536+0+0
2048x1536      60.0*+

Sadly true prefered resolution should only be 1920x1080.

When selecting a resolution of 2048 x 1536, it looks like I got a 1920x1080 resolution but some part of my desktop is missing.

I suspected the panning was the cause of my problem and tried:

Code:

xrandr --output LVDS-1 --panning 1920x1080

To this effect:

Code:

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  149 (RANDR)
  Minor opcode of failed request:  29 (RRSetPanning)
  Serial number of failed request:  29
  Current serial number in output stream:  29

What I tried yet:
- changing panning (failed)
- changing screen size -fbmm/-fb (no effect)

What I did not try:
- download proprietary driver

Any idea on how to solve this issue?

Sounds like the usual EDID issue. Some TV's don't identify themselves properly over various connections. For example, my TV's EDID is only detected properly over HDMI, not VGA. For others, it's vice versa. How are you connecting your machine to that 1080p display, HDMI, DVI, or VGA?

My post wasn't clear: its about my laptop screen.

Switching to Nvidia proprietary driver solved my issue and my screen is now properly sized.
It looks like Nouveau driver mistook the max VGA screen size my graphic card can handle for the actual screen size.
