Acer AL2216WBD 22in Wide Screen

Postby cullen on Fri Feb 01, 2008 11:06 pm

I recently swapped my old CRT monitor for an Acer AL2216WBD 22in Wide Screen, how do I tell Mint that I've changed displays?

I have tried
sudo dpkg-reconfigure xserver

and it ran me through a wizard, I plugged in the hoz and vert fequency ranges and selected the available resolutions as provided by the owners manual, but I am still unable to get true wide screen support. Any suggestions?

Wide screen seems to be a bit of a problem
You used horizontal and vertical refresh values from the manual?
Then it seems we can exclude one common error.
Tell us which video card you have and post your xorg.conf

Sorry for the delayed response time.

I formatted and reload this machine to Daryna.

But I still can't get the monitor to accept an "optimal resolution" of 1680x1050, but 1600x1200 is working.

I'd like to get ther other to work so here's what you wanted to know.

This machine is using a Nvidia Geforce-Fx 5200 256mb Graphics card.

Here are the relevant sections of my xorg.conf

Code: Select all
Section "Device"
   Identifier   "nVidia Corporation NV34 [GeForce FX 5200]"
   Driver      "nvidia"
   Busid      "PCI:1:0:0"
   Option      "AddARGBVisuals"   "True"
   Option      "AddARGBGLXVisuals"   "True"
   Option      "NoLogo"   "True"
EndSection
Section "Monitor"
   Identifier     "Generic Monitor"
       ModelName      "Acer AL2216W"
       HorizSync       30.0 - 82.0
       VertRefresh     56.0 - 76.0
       Option         "DPMS"
EndSection
Section "Module"
   Load      "glx"
EndSection

xorg.conf is OK and nvidia no problems....
May be that the resolution is to far off from what's expected
If you use only one monitor add
Code: Select all
Option       "DynamicTwinView" "False"

to section "Device" makes a difference but not for your problem
One way would be to use a modeline
I've got one for you if you want to use 60Hz vertical
Horizontal Resolution: 1680
Vertical Resolution: 1050
Vertical Refresh Rate: 60.00 Hz
Horizontal Refresh Rate: 65.35 KHz
Dot Clock Frequence: 149.00 MHz

Code: Select all
# V-freq: 60.00 Hz  // h-freq: 65.35 KHz
 Modeline "1680x1050" 149.00  1680 1760 1944 2280  1050 1050 1052 1089

75 is out of range, 70 would be
Code: Select all
# V-freq: 70.00 Hz  // h-freq: 76.72 KHz
 Modeline "1680x1050" 185.97  1680 1776 2000 2424  1050 1050 1053 1096

This is no first hand solution, but you could try it
You add it at the end of section Monitor

Did you go into the screens and graphics preferences and change the Model to LCD Panel
either the Acer wide screen you have or to the Generic LCD Panel 1680x1050 (wide screen)
Often there is a box to check for wide screen
With my 22" it requires this change in some Debian based distro's also you will need to log out
