samsung 2232bw and asus a8js (nvidia 7700)

[broady]

Hey there,

i am new on this forum and this is my first thread.

I have got an nvidia 7700 on my laptop and i am trying to set it up with a 22" samsung 2232bw. Drivers for my videocard work correctly.

If i connect my monitor with vga it work fine. At the start the samsung is active, laptop lcd is off and i can set the max resolution (1680x1050) without problems via nvidia-settings. Now i wanna connect it vis dvi since my goal is a dual monitor: the 22" on the dvi and an other 19" on the vga. So first i'd like to go just with the 22" on the dvi.

When i connect it via dvi, at the start the 22" is disabled (i can see all just when kubuntu is loading but when i have to login it turns to black). I can activate it via nvidia-settings and reach the max res. without problems. All seems fine but when i try to see any video on my pc kubuntu freezes.

I have read a lot about this monitor and kubuntu, nothing worked. I will post my xorg.conf:

# xorg.conf (xorg X Window System server configuration file)
#
# This file was generated by dexconf, the Debian X Configuration tool, using
# values from the debconf database.

Of course the generic monitor section refers to the laptop panel.

Sometime i crash when i exec a video and sometime it's ok.
The question is: what has a video more than usual applications that can make kubuntu crash?
NOTE: with this xorg.conf when i turn on my pc the samsung is enabled and the laptop's panel is disabled. All right here

The crash on playing a video does not necessarily mean your graphics driver and /etc/X11/xorg.conf file have a problem. It looks OK -- it may be fine.

What kind of video? What player are you using to play it?

thanks for replay.

They are normal videos, many of em are avi. If i use the vga mode there is no problem at all. Moreover it's not a player issue, it's the same if i use vlc or kaffeine.

Have a nicw day

Re: samsung 2232bw and asus a8js (nvidia 7700)

Have you tried letting the Nvidia xorg utility write a new xorg.conf file? If you want to try it, first make a backup copy of your existing xorg.conf file.

Then, leave the Samsung connected, and open a Konsole window. Enter

sudo nvidia-xconfig

and it will write a new xorg.conf file, hopefully suitable to both displays.

Then restart the X server with Ctrl-Alt-Backspace, log back in and do some experiments to see how well it works.

If you want to be brave, you can also try it like this:

sudo nvidia-xconfig --add-argb-glx-visuals --composite

to add GLX and compositing capability. Some cards benefit from this, and some don't. There are other things you can do with the xorg.conf driver options -- you can read the Nvidia manual for your driver and learn about the options for twinview, etc.

well i didn't do the exact same thing but something like that: booted with the samsung connected via dvi, from nvidia-settings, disbaled the laptop's lcd and enabled the 22" at max resolution. So i did "save the current configuration in xorg.conf". The resulting xorg.conf is the second one posted by me (the short one).

It seems good since there are 2 monitor sections and 2 screen ones.

The problem stays but, sometime i crash sometime i don't.
