Low resolution on install

#1 Post by odenproser »

Hey there,

I am an 'intermediate level' linux user, trying Debian 9 XFCE on an oldish ASUS A52J laptop; I've run into a display issue.

Resolution is limited to 1024x768 but the display supports 1366x768. xrandr didn't seem to do the trick.

Code: Select all

xrandr -s 1366x768
Size 1366x768 not found in available modes

Code: Select all

cvt 1366 768
# 1368x768 59.88 Hz (CVT) hsync: 47.79 kHz; pclk: 85.25 MHz
Modeline "1368x768_60.00"  85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync

Code: Select all

xrandr --newmode "1368x768_60.00"  85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync
xrandr: Failed to get size of gamma for output default
Is this a driver issue? Can anybody help?

Thank you.

What is the GPU model ?
If it is ATI/AMD, you may need to install the firmware-amd-graphics package from the non-free section.

I'm getting an error:

Code: Select all

sudo apt-get install firmware-amd-graphics
bash: sudo: command not found
Same if I substitute apt-get for apt.

Without sudo I'm getting E: Could not open lock etc..

^ You need to add the non-free component to your sources, consult Debian's extensive documentation for more on this.

EDIT: here's a bone, doggie:

Does my ability to issue a root command, destroying a system with one press of the enter key make me an advanced user? :lol:

Who was it that criticized my suggestion of having someone just directly download and install a firmware deb?
