xrander problem with 1900x1080p
- by Eslam
i have a problem with xrandr
i successfully executed the following :
#cvt 1900 1080
#xrandr 1900x1080 170.75 1904 2024 2224 2544 1080 1083 1093 1120 -hsync +vsync
but unfortunately the following command :
#xrandr --addmode VGA-0 1900x1080
returned the following error :
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 153 (RANDR)
Minor opcode of failed request: 18 (RRAddOutputMode)
Serial number of failed request: 29
Current serial number in output stream: 30
the following command output might help in identifying problem :
#glxinfo |grep -i opengl
OpenGL vendor string: NVIDIA Corporation
OpenGL renderer string: GeForce 310M/PCIe/SSE2
OpenGL version string: 3.3.0 NVIDIA 310.14
OpenGL shading language version string: 3.30 NVIDIA via Cg compiler
OpenGL extensions:
#lspci |grep -i vga
01:00.0 VGA compatible controller: NVIDIA Corporation GT218 [GeForce 310M] (rev a2)
any ideas what's gonna be wrong ?
