Default Video Monitors

Does ububtu use
special drivers for monitors like Windows XP?


*


How do I get my ubuntu
installations to recognise my LCD monitor and let me set the required resolution?


*

Generally it just uses "plug and play", but my Benq FP94G wasn't recognized
in kernel 2.6.22 (gutsy) and I don't think in 2.6.24 (which are the kernels
in Hardy), but it is in 2.6.26

Try explaining what you've done, and what you're seeing (not to mention what
monitor and graphics adapter you have).

Indeed. I suspect it is just as likely to be an issue with the video
card driver than the monitor itself.

If you have an ATI or NVIDIA card, are you using the OSS or closed
source binary drivers ? If the former, try installing the later

you need to configure your xorg.conf to the resolutions you want your
lcd to display.

However on all the systems i use, the default driver works just fine
with the lcd

Here is an example of what your xorg screen section should look like.

Section "Screen"
Identifier "Default Screen"
Device "NVIDIA Corporation NV34 [GeForce FX 5200]"
Monitor "CM752ET"
DefaultDepth 16
SubSection "Display"
Depth 16
Modes "1024x768_75.00"
EndSubSection
EndSection

I would not recommend copying and pasting this section into your xorg as it may
cause problems

Default Video Monitors

The monitor I am using is an ACER AL707. On both boxes I installed
ubuntu from an iso taken from the APC magazine DVD. I then upgraded from
the internet. The results on the two boxes are different.

On one box ubuntu boots, and to see a menu I need to press escape. The
menu options are:
Ubuntu 8.04.1, kernel 2.6.24-19 Generic
Ubuntu 8.04.1, kernel 2.6.24-19 Generic - recovery mode
Ubuntu 8.04.1, kernel 2.6.24-16 Generic
Ubuntu 8.04.1, kernel 2.6.24-16 Generic - recovery mode
Ubuntu 8.04.1, Memtest86+

Since I only installed form one Iso I do not understand why I have two
versions of the Kernel, but perhaps this was created by the updates.

On the second box the menu is displayed without needing to press escape.



On the first box the processor is Pentium 4, 2.4g with 480 Mbyte ram.
I suspect this box has an on board video.
On selecting first menu option the monitor first displays a message
saying Input not Valid, eventually id displays the login screen, but the
monitor the goes into autoconfig mode. Once logged in the best
resolution offered is 960 x 600.

On the second box which has 728 Mbyte ram and a nvidia TN vidieo card
with 32 M ram, the menu displays without the need to press esc. After
choosing the first menu option the screen is set to 800 x 600


Note that the resolution of the screen on the XP box is 1152 x 864.

All three machines are connected to the same monitor, keyboard and mouse
by an electronic switch.
Whenecer I select the firsat Linux box the monitor is set into
autoconfigure mode

If I boot the machine with the Nvidia card using the 2.6.24-16 kernal
then it opens in 800x600 but I can change the resolution using
preferences to 1280 x 1024.

On the other machine with mother board video this makes no difference.
I would like to get the higher resolution options on both machines. Can
anyone suggest what I need to do?

Regards


Peter Goggin

Peter - I'd suggest booting one of the problem computers without the
KVM switch. I do know some KVM units cause issues with the video
card not communicating with the monitor correctly.

One of the boxes originally had RedHat 7.3 and was used as a web server.
When I got the LCD monitor this worked without any problem using the
KVM. It was only after I installed Ubuntu, cleaning out the RedHat that
the problem started on this machine. The other machine originally had XP
professional and I overwrote this with ubuntu, again clearing the XP.
Again this machine worked with the monitor connected with the KVM,
before changing to ubuntu.


I believe the problem lies with the drivers in the ubuntu distribution
which do not properly recognise the monitor (ACER AL707 LCD)
