Troubleshooting Display Resolution @ Ubuntu - Debian and families
I will not responsible if the result you got will be different and you get some trouble. But these steps really working for me.
.
I really irritated after find that ubuntu 17 xenial limit my monitor resolution to 1024x768 usually it is about 1360x768 at less. I thinks the caused is the Radeon Driver,
but radeon stop release the driver for linux. Later I know that Ubuntu bundled Radeon driver with every new release. In one day after some trial and error my monitor goes blank and give some error that force me to reinstall Ubuntu, since that day I become more carefully to take action about driver. Today I found a solution. Goto terminal and type
First step type
#cvt 1360 768
it show message 1360x768 59.80 Hz (CVT) hsync: 47.72 kHz; pclk: 84.75 MHz
Modeline "1360x768_60.00" 84.75 1360 1432 1568 1776 768 771 781 798 -hsync +vsync
.
.
Second step type
#xrandr --newmode "1360x768_60.00" 84.75 1360 1432 1568 1776 768 771 781 798 -hsync +vsync
.
NOTE: Just type "xrandr --newmode" then copy paste the line from the message showed before
.
.
Third step type
#xrandr --addmode VGA-0 1360x768_60.00
.
The monitor may be flip and show just black display for some seconds, after that the monitor new resolution will be enjoyable.
