Description xuji 2007-03-21 19:10:16 UTC 
The xrandr options "--delmode --addmode --rmmode" don't work with following info given:

[root@x-915gm at]# xrandr --delmode LVDS 0x69
X Error of failed request:  BadAccess (attempt to access private resource denied)
  Major opcode of failed request:  156 (RANDR)
  Minor opcode of failed request:  19 ()
  Serial number of failed request:  16
  Current serial number in output stream:  17
Comment 1 Gordon Jin 2007-08-21 00:10:28 UTC 
This issue still exists with the latest code.
Comment 2 Keith Packard 2007-08-21 00:33:44 UTC 
Modes created and managed by the X server cannot be deleted by the user. Only user-created modes may be deleted.
Comment 3 WuNian 2007-08-21 22:14:01 UTC 
If use user-defined mode, the --newmode --addmode and --delmode work correctly, but --rmmod still can not work. Below is my commands:

Keith Packard, I have a similar issue. I can't delete mode managed by the X server even by root with sudo.

I have the following issue. I have macbook pro 2015 retina with highest possible resolution in macOS = 1920x1200. But I have the following in linux:

Screen 0: minimum 8 x 8, current 5760 x 1200, maximum 32767 x 32767
eDP1 connected 1920x1200+3840+0 (normal left inverted right x axis y axis) 330mm x 210mm
   1920x1200     59.88 +  60.00* 
   2880x1800     59.99 +
   2560x1600     60.00  
   2048x1536     60.00  
   1920x1440     60.00  
   1856x1392     60.01  
   1792x1344     60.01  
   1600x1200     60.00  
   1680x1050     60.00  
   1400x1050     59.98  
   1280x1024     60.02  
   1440x900      60.00  
   1400x900      60.00  
   1280x960      60.00  
   1280x800      60.00  
   1024x768      60.00  
   800x600       60.32    56.25  
   640x480       59.94  

The only custom resolution here is 1920x1200 - it didn't appear automatically for some reason. 2880x1800 has correct proportions (16x10) (and even works on 15.4'' display), but too high - not comfortable to work (and interesting that macOS can't use it).

Most of other resolutions look buggy with black corners (1920x1440 is not 16x10, it is 4x3). I want to remove them once and for all - sometimes laptop turns on 2880x1800 automatically when I am attaching second/third monitor - this is very confusing. I want to 1920x1200 to be default and hightest possible.

It looks like a bug - but I have no idea where - xrandr? X server? xf86-video-intel? kernel?

That's what I see from Xorg.0.log:

I can create a bug in another project - but don't know where. Ideally I want to ignore these wrong autodetection and configure anything manually. I tried to add
  Option  "PreferredMode" "1920x1200"
to the Monitor section and 
   Option      "UseEDID" "false"
   Option      "UseEDIDFreqs" "false" 
to the Device section. Nothing helped.
