Acer AL1711 monitor not working under Mandriva


I cannot get my newly bought Acer AL1711 monitor to work under Mandriva. After booting I see a black screen with the monitor's message saying: Input not supported, after that I just have to manually shut down the PC as I can't see anything on the screen. BTW, I can hear the start up sound only.
The monitor works fine under WinXP.
Could someone suggest what might be wrong? The monitor didn't come with any drivers on the CD.
Thanks for your input.

You need to reconfigure your xserver. When you get to the black screen, do CTRL-ALT-F1 (or any number upto 6), Login as root, do "init 3" and run "xorgconfig". When you have reconfigured your xserver, run "init 5" to get back to gui mode.

Hi, i have similar problem.. I have ran xorfcofig, set everything okay and its still the same.. Nothing
If I set 1024*768 resolution, i get proper image, but still message box "input not supported" is going on the screen which is so annoying
If I set 1280*1024(native resolution of my LCD) i get only message box "input not supported" ( So I'm in 800*600..
I have Matrox G550 Dual Head and I'm using digital output..

THX for every ideas..

Try using drakx to configure your xserver if you can login to a gui.

Possible Solution: different ACER monitor, same problem.

I've got a 22" ACER AL2223W that had the same problem. Turns out it is XFree86 not knowing the right mode. This is on an ancient RedHat 9 box. I looked in my /var/log/XFree86.0.log and found that it recognized the display and reported a lot of useful data:

(II) R128(0): Supported additional Video Mode:
(II) R128(0): clock: 149.0 MHz Image Size: 474 x 296 mm
(II) R128(0): h_active: 1680 h_sync: 1784 h_sync_end 1960 h_blank_end 2240 h_border: 0
(II) R128(0): v_active: 1050 v_sync: 1053 v_sync_end 1059 v_blanking: 1089 v_border: 0
(II) R128(0): Ranges: V min: 56 V max: 76 Hz, H min: 31 H max: 82 kHz, PixClock max 150 MHz
(II) R128(0): Monitor name: AL2223W
(II) R128(0): ACER

From this, I could construct the horizontal sync and vertical refresh ranges, the display size and the correct mode line for this monitor. I ended up using this section in my XF86Config:

Section "Monitor"
Identifier "Monitor0"
VendorName "ACER"
ModelName "AL2223W"
DisplaySize 474 296
HorizSync 31 - 82
VertRefresh 56 - 76
Option "dpms"
ModeLine "1680x1050" 149 1680 1784 1960 2240 1050 1053 1059 1089
EndSection

That lets it use the LCD's native resolution mode. You can see which numbers I pulled from the log messages to construct all that. I would expect that with different monitors you would need different numbers, but the principle is the same as long as you can get the data out of your X server.

The same section worked in my xorg.conf on a newer Gentoo 2006 distro that had the same "Input not supported" message. But the Xorg server did not give me the same sort of messages, but perhaps Xorg -configure will get the right data for you.

Yes, I know I'm replying to an ancient message, but I pieced this all together with the help of about 30 posts on 10 different forums, so now I'm putting the whole solution out there as a single post so folks can find it easier.
