beaglebone black ubuntu display x11 server的配置
I'm running a BeagleBone with a 5,7" LCD Touchscreen with a native resolution of 640x480
However, the system recognizes monitor as a LCD7 Cape with 800x480
resolution and after LXDE boot desktop is only partially displayed
On the old 12.04 FBDEV was used and I fixed problem adding the /usr/share/X11/xorg.conf.d/10-monitor.conf this way :
Section "Monitor"
Identifier "Configured Monitor"
EndSection
Section "Screen"
Identifier "Default Screen"
Device "Configured Video Device"
Monitor "Configured Monitor"
#Limited by SGX?
DefaultDepth 16
SubSection "Display"
Modes "640x480"
EndSubsection
EndSection
Section "Device"
Identifier "Configured Video Device"
Driver "omapfb"
Option "fb" "/dev/fb0"
EndSection
With new kernel on 13.10 or 14.04 it seems FBDEV is no more used but modesetting is, instead.
So the old 10-monitor.conf is useless.
/var/log/Xorg.0.log from 12.04 is :

How I can fix resolution in 13.10 ??
Can I still use 10-monitor.conf ? which settings ??
Thank you very much.
Just instruct which modeline to use in 10-monitor.conf this way :
Start lXterminal in lxde environment and issue the command
cvt 640 480 60 (horizontal - vertical - rate)
its output will be something like:
# 640x480 59.38 Hz (CVT 0.31M3) hsync: 29.69 kHz; pclk: 23.75 MHz
Modeline "640x480_60.00" 23.75 640 664 720 800 480 483 487 500 -hsync +vsync
create a new /usr/share/X11/xorg.conf.d/10-monitor.conf inserting the copied RED line in Monitor section this way :
Section "Monitor"
Identifier "Monitor0"
Modeline "640x480_60.00" 23.75 640 664 720 800 480 483 487 500 -hsync +vsync
EndSection
Section "Device"
Identifier "Device0"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 16 #Choose the depth (16||24)
SubSection "Display"
Depth 16
Modes "640x480_60.00" #Choose the resolution, match the Modeline
EndSubSection
EndSection
Save and reboot,
it worked for me, hope it helps someone with this problem.
