can't change my screen resolution, crtc0 failed

#1 Post by getehen »

Hello,
I've a problem with my screen, if I try to change its resolution to 1920x1080 (it's a 16:9 screen, 1920x1080), it say to me "configure crtc 0 failed"

Code: Select all

gtn@GtNDEBIAN:~$ cvt 1920 1080
# 1920x1080 59.96 Hz (CVT 2.07M9) hsync: 67.16 kHz; pclk: 173.00 MHz
Modeline "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
gtn@GtNDEBIAN:~$ xrandr --newmode "1920x1080_60.00"  173.00  1920 2048 2248 2576  1080 1083 1088 1120 -hsync +vsync
xrandr: Failed to get size of gamma for output default
gtn@GtNDEBIAN:~$ xrandr --addmode default "1920x1080_60.00"
xrandr: Failed to get size of gamma for output default
gtn@GtNDEBIAN:~$ xrandr --output default --mode "1920x1080_60.00"
xrandr: Failed to get size of gamma for output default
xrandr: Configure crtc 0 failed
gtn@GtNDEBIAN:~$ 


I looked for the solution on many forums but I didn't found it...
Anyone can help me ?
