Hi guys,
I'm dealing with this issue for weeks, please give me a feedback about it.
Unexpectedly, one day:
- the monitor's resolution was restricted to 1024x768 (4:3)
- HDMI didn't work anymore
- display configuration appears as "unknown"
- when trying to use a samsung TV as a second monitor (VGA PC input) it starts showing a message like "unsupported resolution"
everything was working well ... until that horrible day :-(
My monitor is ACER AL1916W, there is NOT an NVIDEA card, fedora was FC17, so i decided to upgrade it to fc18, but the problem is still happening.
I tried to change the resolution (configuration) by modifying /etc/X11/xorg.conf.d, to:
Code:
#cat 30-graphic.conf
Section "Device"
Identifier "Intel Integrated"
Driver "intel"
EndSection
#cat 40-monitor.conf
Section "Monitor"
Identifier "VGA1"
Modeline "1440x900_60.00" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync
Option "PreferredMode" "1440x900_60.00"
EndSection
#cat 50-screen.conf
Section "Screen"
Identifier "Default Screen"
DefaultDepth 24
SubSection "Display"
Depth 24
Modes “1440x900"
EndSubSection
EndSection
but, on boot, it goes to a black screen.
i can change resolution by command lines, but it is not persistent and problems about HMDI, VGA and "unknown monitor" continues happening:
Code:
#cvt 1440 900
#xrandr --newmode "1440x900_60.00" 106.50 1440 1528 1672 1904 900 903 909 934 -hsync +vsync
#xrandr --addmode VGA1 1440x900_60.00
#xrandr --output VGA1 --mode 1440x900_60.00
Code:
#uname -a
Linux duke8814 3.9.11-200.fc18.i686 #1 SMP Mon Jul 22 21:29:25 UTC 2013 i686 i686 i386 GNU/Linux
comments are wellcome, i am planing to move to fc19 after solving this issue,
thanks in advance
Hector
