Vlocity not wanting to give me correct screen resolution

[Herpy]

I use my 55 inch tv as a monitor. I need a resolution of 1920x1080. Vlocity only gives me 1020x780. Anyway to force it?

Hi Herpy, welcome back!

Take the easy path first, check with xrandr if your resolution is supported:

Code:

vlocity 福 ~
3990 ◯ : xrandr                                                                                                                                                                                                   
xrandr: Failed to get size of gamma for output default
Screen 0: minimum 320 x 240, current 1920 x 1080, maximum 1920 x 1080
default connected 1920x1080+0+0 0mm x 0mm
   1920x1080      50.0*
   1024x768       51.0     59.0     60.0 
   1680x1050      52.0 
   1400x1050      53.0     54.0 
   1280x1024      55.0     56.0 

If you find your desired resolution, you can try to use it like this:

Code:

xrandr --output default -s <x size>x<y size>x<refresh rate>

If your resolution is not listed, that usually means that your video card cant query the monitor for configuration values.
This method worked for me:

 * Find the right values for HSync and Vertical Refresh from your monitor manual, and also the signs for each one (note +hsync and +vsync in the code, in my manual are specified as "+/+" after the refresh rate).
 * Create a modeline with cvt in the command line:

Code:

vlocity 福 ~
3989 ◯ : cvt 1920 1080 60                                                                                                                                                                                         
# 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

Note that cvt provides wrong signs for hsync and vsync, I replaced those with the values from my manual.
Now with this data written down, move to the next step:

 * Create a Monitor section in /etc/xorg.conf (create the file if it doesnt exist).

Code:

Section "Monitor"
    Identifier     "My Monitor"
    HorizSync       30.0 - 83.0
    VertRefresh     56.0 - 75.0
    Modeline     "1920x1080" 173.00  1920 2048 2248 2576  1080 1083 1088 1120 +hsync +vsync
EndSection

Save and restart X. This was the only method that worked for me, HTH!

I could not figure it out so I installed Vector Linux STD Gold with pae. And yes it supports my resolution, but I will keep that noted. I will give it another shot in the future.
