Description Lee Leahu 2012-01-22 22:03:58 UTC

XRANDR is failing to scale the output as requested.

Step #1 - Check the current resolution:

# xrandr
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 320 x 175, current 1280 x 1024, maximum 2560 x 2048
default connected 1280x1024+0+0 0mm x 0mm
   1280x1024      50.0*    51.0     52.0     53.0  
....


Step #2 - Try scaling the output to the current size (1x1):

# xrandr --output default --scale 1x1
xrandr: Failed to get size of gamma for output default
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  151 (RANDR)
  Minor opcode of failed request:  26 (RRSetCrtcTransform)
  Value in failed request:  0x160
  Serial number of failed request:  20
  Current serial number in output stream:  21


Step #3 - Try scaling the output to be 1/2 the current size (0.5x0.5):

# xrandr --output default --scale 0.5x0.5
xrandr: Failed to get size of gamma for output default
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  151 (RANDR)
  Minor opcode of failed request:  26 (RRSetCrtcTransform)
  Value in failed request:  0x160
  Serial number of failed request:  22
  Current serial number in output stream:  23


Step #4 - Try scaling the output to be 50% larger than the current size (1.5x1.5):

# xrandr --output default --scale 1.5x1.5
xrandr: Failed to get size of gamma for output default
X Error of failed request:  BadValue (integer parameter out of range for operation)
  Major opcode of failed request:  151 (RANDR)
  Minor opcode of failed request:  26 (RRSetCrtcTransform)
  Value in failed request:  0x160
  Serial number of failed request:  21
  Current serial number in output stream:  22

I've performed some troubleshooting and (excluding the nvidia driver specific messages in the log file) am getting the same behavior using the VESA 2.3.0 driver.

Comment 4 Lee Leahu 2012-01-23 10:10:23 UTC

Hi - I have another computer running Ubuntu 11.04 that does not have this problem.  It is running the following packages:

Xorg-server 1.10.1
Xrandr app – 1.3.1
Xrandr lib – 1.3.1

Comment 5 Aaron Plattner 2013-02-06 18:30:22 UTC

I think this is expected for xf86-video-vesa and the older NVIDIA driver you tried because they don't support configuring scaling via RandR.  Please try a newer NVIDIA driver version.

My system details have changes since I opened this ticket.

My system details are now:

OS: Linux 3.6.11, 64-bit
GLIBC: 2.15-r3

Video card:  NVIDIA Corporation GF116 [GeForce GTX 550 Ti] (rev a1)

Xorg-server: 1.13.1
NVIDIA Drivers:  310.19

I am running Twinview and the following command works without issues:

# xrandr --output DVI-I-2 --scale 1.5x1.5 --output DVI-I-3 --scale 1.5x1.5
