Cant change resolution more than 1024x768

g3ck0 · 2016-05-17 05:31:21

Hi, I have a LG 20M35A-B monitor (1600x900) and GTX 660, that monitor doesnt have DVI so I'm using a VGA to DVI adapter.
With Nouveau driver I cant go more than 1024x768, with nvidia driver max. resoultion is 800x600, and with nvidia-beta 640x480. What I can do?

I already try putting 1600x900 within nvidia-settings but it looks distorted, probably because the refresh rate.

thanks!!!

Yeah, thanks, got it. Problems anyway
1600x900 font seems too... blurry? And, when I create the 10-monitor.conf system doesn't start...

Please post the full content of the troublesome .conf file.

EDIT: please also post the relevant Xorg log file.

Okay I'll put everything may seem relevant.

This is my 10-monitor.conf

Section "Monitor"
    Identifier "DVI-I-1"
    Modeline "1600x900_60.00"  118.25  1600 1696 1856 2112  900 903 908 934 -hsync +vsync
    Option "PreferredMode" "1600x900_60.00"
EndSection

Section "Screen"
    Identifier "Screen0"
    Monitor "DVI-I-1"
    DefaultDepth 24
    SubSection "Display"
        Modes "1600x900_60.00"
    EndSubSection
EndSection

Section "Device"
    Identifier "Device0"
    Driver "nouveau"
EndSection

With this my system doesn't start. Only gave me a prompt, where I can delete /etc/X11/xorg.conf.d/10-monitor.conf to start the system in 1024x768.

Adding res (blurry!!):

 $ cvt 1600 900

# 1600x900 59.95 Hz (CVT 1.44M9) hsync: 55.99 kHz; pclk: 118.25 MHz
Modeline "1600x900_60.00"  118.25  1600 1696 1856 2112  900 903 908 934 -hsync +vsync

$ xrandr --newmode "1600x900_60.00"  118.25  1600 1696 1856 2112  900 903 908 934 -hsync +vsync

$ xrandr --addmode DVI-I-1 1600x900_60.00

$ xrandr --output DVI-I-1 --mode 1600x900_60.00

Thank you very muchhhhh!!

But when you use the `xrandr` commands, the resolution changes, correct?

Are you using the nouveau driver here?

If you create a 10-test.conf with just the last stanza in it:

Section "Device"
    Identifier "Device0"
    Driver "nouveau"
EndSection

Does your desktop still start (at the low resolution)?

Mm... I think it says "Cant open display"

Working!

Interestingly, today I went back to try my 10-monitor.conf and suddenly it worked.

But the problem of blurry persist. I don't know if it's because cvt values

cheers!!
