How to change display resolution in Xfbdev?

Hi

I can see my 64bit Tinycore is using Xfbdev.
The resolution is definitely set too low (probably 1360x768).  I cannot figure out how to set the resolution to my Thinkpad's 1600x900 display.  Any ideas? Thanks.

Xfbdev uses the framebuffer's resolution. How to set that depends on what framebuffer are you using (vesa, efi, or kms).

After I installed the graphics-6.6.8-tinycore64.tcz and rebooted, the display resolution automatically become 1600x900.  Everything looks good now.

My laptop have Intel graphics and a 4th gen i5 CPU.

Btw, is there software  to dim the backlight on my LCD panel?

Thanks!

Hi euless
You could try this:

--- Code: ---tce-load -wi Xorg-7.7-bin
--- End code ---

Then see if this sets the brightness to 75 percent:

--- Code: ---xbacklight -set 75
--- End code ---

Otherwise, see if  /sys/class/backlight/  contains any directories or files.

Yeah, changing the values in /sys/class/backlight/brightness works.   

Is /opt/bootlocal.sh the proper place to set the backlight brightness at boot time?

I.e.
--- Code: ---echo 2000 > /sys/class/backlight/brightness
--- End code ---
