Add support Samsung 244T and pb with extended dual screen

[Typhoe]

Binary package hint: displayconfig-gtk

Hi,

I own a compaq notebook with an ati card
lspci |grep VGA
01:00.0 VGA compatible controller: ATI Technologies Inc Radeon RV250 [Mobility FireGL 9000] (rev 01)

My notebook screen is a 1400x1050 one.

I have a second screen, a LCD Samsung SM244T 1920x1200.
I use the vga connector to connect it.

First, this screen is not in the database, so please add it (The inf file for it is below).

Second, when a xorg.conf.1 file exists, but no xorg.conf file, the Xserver work, and you can open a session, but displayconfig-gtk won't allow you to do anything:
*********************************************
sudo displayconfig-gtk
fallback mode
*** Error: no screens were specified in the ServerLayout section
*********************************************
displayconfig-gtk launches but you get a "You need administrative rights to change all screen settings" error (although I give the right admin password).

Third, if my second screen is connected at boot (it doesn't need to be on), the ddcprobe and get-edid commands report the specifications of my second screen only, and not the notebook's one.
Thus, although on my notebook screen, I "see" a 1400x1050" display, in fact my screen is set in 1920x1200.
See screenshot_1.png, that's what I indeed see if I switch on my second screen.
The menu bar have the right size, but if I try to maximize a window, I lose the left and bottom of the window because the window use the 1920x1200 resolution and not the 1400x1050.

Forth, now I have unplugged my second screen, reboot, and then plugged it in and launch displayconfig-gtk to add it as an extension of default screen.
My 244T screen is not known, so I add it with its inf file.
I select it, but there is no 1920x1200 resolution ???
Same if I try a Generic LCD Panel 1920x1200.
I only have 1600x1200, 1792x1344, 1856x1392 and 1920x1440, but no 1920x1200 !
Whatever the resolution I choose, after restarting gdm (ctrl+alt+backspace), my gdm session hangup (3 times the command line log appears, and then I have the failsafe screen displayed).
On that menu, if I try to set back to only one screen in 1400x1050, my gdm login screen appears, but the refresh rate is wrong and I can't do anything.
So I have to hit ctrl+alt+F1, stop gdm, put a "clean" xorg.conf (the one from the first boot), and restart gdm.
Then, I have a running gnome session again, but with my seconf screen in "clone mode" in 1920x1200 (same as screenshot_1.png).

Fifth, when displayconfig-gtk run in failsafe mode, you should be able to select the keyboard language setting too.
I use a french keyboard, and each time I started a gnome session after a fail safe, I was back with an us keyboard.

I hope this report will be of some use for you.
Can you do something? Do you need more information? In that case, what exactly?

Regards,
Typhoe

My system is up to date, running Gutsy:

My xorg.conf from scratch.
This one work.

If the second screen is unplugged before boot, all is perfect (meaning, the wallpaper has the right size, and the windows if maximize are in 1400x1050)
If the second screen is plugged before boot, then I have the behavior shown in the screenshoot_1.png picture.

Non-working xorg.conf generated by displayconfig-gtk to set my second screen in extended display 1600x1200

[Typhoe (spamistrash)]

The old xorg.conf file I used in feasty to get my default screen in 1400x1050 and my second screen in 1920x1200.

With this one, a window maximize in the default screen was in 1400x1050 => good
a window maximize in the second screen was in 1920x1200 => good too

Compiz was not working (I could live without it ;) )

Video were working on both screen (I could maximize in fullscreen on either of them) and keep woking on the other.

Notice that I had to use a modeline to get the 1920x1200 resolution to work.

This xorg.conf doesn't work anymore in gutsy.
I get the failsafe mode if I try it.

Most of your issues should be fixed with the next release. Please fill one bug report for each issue in the future. This bug is quite unmaintable.

Cheers,

Sebastian

Thank you, and sorry for the "unmaintable" report.

I'll split next time (yet, I hope there won't be any next time :p)

Thanks for your work.
