I've just discovered an amazing script called "Newrez", which allow me to force any screen resolution (Up to 8000 pixels!!) on my laptop. The main issue is that assuming I select a 1600x1200 resolution (I'm using 1366x768), my mouse remain stuck inside a 1366x768 rectangle. This is a known problem, but I can't figure it out how to fix it. I don't know how to use the script "Newrez-v" proprely.
I would like to add custom resolutions to Ubuntu, but that isn't working. Here's the outpup of the command xrandr:
Output of gtf 1280 800 60:
Screen 0: minimum 320 x 200, current 1366 x 768, maximum 8192 x 8192 LVDS1 connected 1366x768+0+0 (normal left inverted right x axis y axis) 309mm x 174mm panning 1366x768+0+0 1366x768 60.0*+ 1360x768 59.8 60.0 1024x768 60.0 800x600 60.3 56.2 640x480 59.9 VGA1 disconnected (normal left inverted right x axis y axis) HDMI1 disconnected (normal left inverted right x axis y axis) DP1 disconnected (normal left inverted right x axis y axis) 1600x1200_60.00 (0xd5) 83.5MHz h: width 1280 start 1344 end 1480 total 1680 skew 0 clock 49.7KHz v: height 800 start 801 end 804 total 828 clock 60.0Hz
So far, I've tried this:
# 1600x1200 @ 60.00 Hz (GTF) hsync: 74.52 kHz; pclk: 160.96 MHz Modeline "1600x1200_60.00" 160.96 1600 1704 1880 2160 1200 1201 1204 1242 -HSync +Vsync
The terminal return nothing, no error, so I type this:
xrandr --newmode "1600x1200_60.00" 83.46 1280 1344 1480 1680 800 801 804 828 -HSync +Vsync
Now unfortunately, I keep getting this error. I believe this is a known bug:
xrandr --addmode LVDS1 "1600x1200_60.00"
X Error of failed request: BadMatch (invalid parameter attributes) Major opcode of failed request: 150 (RANDR) Minor opcode of failed request: 18 (RRAddOutputMode) Serial number of failed request: 29 Current serial number in output stream: 30
Can you help? What I am doing wrong, here?
Thank you very much!
