Display Resolution issues
I've just installed Neptune5Plasma on a 'play' with platform:
GigaByte motherboard, GA-C1037UN x64bit 4gig RAM
Intel VGA Display adapter onBoard.

with both an HDMI - Sony 32" Television Monitor & Dell 24" VGA

by default the system boots and works fine - on both monitors in the 1024X768 60hz mode.

I have successfully gotten it to change mode to 1920x1080 60hz by creating and running a .sh script that I saved to my desktop.
xrandr --newmode "1920x1080_60.00"  172.80  1920 2040 2248 2576  1080 1081 1084 1118  -HSync +Vsync
xrandr --addmode VGA1 1920x1080_60.00
xrandr --output VGA1 --mode 1920x1080_60.00

I've tried to automate this process so I don't have to run this everytime I boot, without success. I tried creating an .xprofile - added the code, then going into autostart and scheduling to run my desktop .sh on boot, and or before session. None of these attempts have worked. I was even kinda locked out, when the last method used, resulted in a BLACK screen - without a way to remove my autostart modifications. I had to go in using restore option during boot - and delete the file in /.config/plasma-workspace/env.

I was then able to get back to a working desktop - to square 1.

Once I run my script I notice that the Display settings GUI then contains the mode I added 1920x1080. Even though I go in change back and forth - and apply - upon reboot that selection is gone & the highest resolution again is 1024x768 the default.

How can I make this added mode stick?Huh

RE: Display Resolution issues
You can add the modeline to the xorg.conf file for it to permanently stick.
See this wiki entry with the modeline stuff specifically
