Unable to change the refreshrate to 60hz panel:LQ156M1JW09

I can't seem to change my laptop display's refreshrate to 60hz from 240hz, xrandr reports 60hz but it stays at 240hz,
resolution is changing perfectly.

glxgears displays 240hz, while i can clearly see that it isn't 60hz   yikes

I have tried the these modelines from the following sources

cvt:

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

modelines from xf86-video-intel log @ /var/log/Xorg.0.log

also tried modes from here https://github.com/linuxhw/EDID/blob/ma … 89A3F33AB5

Please use [ code ] rather than [ quote ] for posting outputs. Post the exact xrandr command you are using, maybe also try with the modesetting rather than the intel xorg driver.

Re: Unable to change the refreshrate to 60hz panel:LQ156M1JW09

I have tried with modesetting driver too but no luck.

i have tested the modelines using :

xrandr --newmode "INTEL1920x1080_60.00"  133.32  1920 1944 1984 2000  1080 1083 1088 1111 -hsync -vsync

xrandr --addmode eDP1 INTEL1920x1080_60.00

xrandr --output eDP1 --mode INTEL1920x1080_60.00

Re: Unable to change the refreshrate to 60hz panel:LQ156M1JW09

Well, this should have added add a mode with 133.32 MHz.
What's the output of 

xrandr

after you ran the two commands above?
PS: You can also let the correct mode line be calculated by gtf:

gtf 1920 1080 60

gtf gives me this 

gtf 1920 1080 60

  # 1920x1080 @ 60.00 Hz (GTF) hsync: 67.08 kHz; pclk: 172.80 MHz
  Modeline "1920x1080_60.00"  172.80  1920 2040 2248 2576  1080 1081 1084 1118  -HSync +Vsync

still no luck.

FYI,

I have tested the mentioned modelines with modesetting driver as well

Re: Unable to change the refreshrate to 60hz panel:LQ156M1JW09

@kunver400: Why are you trying to define new modes? According to your xrandr output and Xorg log file, there is already a 60Hz mode. Does that 60Hz mode not work for you? You should normally be able to switch to it with a command line like the following:

xrandr --output eDP1 --mode 1920x1080 --rate 60

About defining new modes, you could try to do that with an Xorg config file like this instead of "xrandr --newmode":

Section "Monitor"
    Identifier "eDP1"
    # 1920x1080 @ 60.000 Hz Reduced Blank (CVT) field rate 60.000 Hz; hsync: 66.660 kHz; pclk: 133.32 MHz
    Modeline "1920x1080_60"  133.32  1920 1928 1960 2000  1080 1097 1105 1111 +hsync -vsync
    #Option "PreferredMode" "1920x1080_60"
EndSection

The "Identifier" name is used to target a certain monitor output. You save this kind of file as for example "/etc/X11/xorg.conf.d/10-monitor.conf".

I created that with a tool "cvt12" from the AUR with this command line:

$ cvt12 1920 1080 60 -b
# 1920x1080 @ 60.000 Hz Reduced Blank (CVT) field rate 60.000 Hz; hsync: 66.660 kHz; pclk: 133.32 MHz
Modeline "1920x1080_60.00_rb2"  133.32  1920 1928 1960 2000  1080 1097 1105 1111 +hsync -vsync

@Ropid

yes, xrandr default modes are not working for me,just now tried modelines from cvt12 , can't seem to resolve this, i must be missing something.
