Hi guys;

I am a bit experienced on Sarge. But new to etch.

Installed on my old laptop Toshiba Satellite 4090 (Celeron400). Display Chipset: Trident Cyber 9525.

I recognized X server system changed to X.org.

I installed X.org and xfce4 from Netinstall CD. But the screen resolution is only 640x480, and this is the only option in my xfce4. I can edit xorg.conf file manually.

I can do the reconfiguration:
dpkg-reconfigure xserver-xorg

And recover the file by:
dexconf -o /etc/X11/xorg.conf

I can use all these tricks... But nothing changes. My desktop is still 640X480. Here is my last xorg.conf file:

Thanks for you all...

Does dpkg-reconfigure xserver-xorg generate that 'driver' selection by itself, or did you insert it? Maybe run it again, and try using a generic driver (Vesa?).

You don't seem to have the HorizSync and VertRefresh lines in your monitor configuration. If your laptop's manual doesn't tell this info, you could try Kanotix (that uses Xorg, IIRC) and see if it gives you a better screen resolution, and then grab the HorizSync & VertRefresh values from Kanotix's xorg.conf.

Then run "dpkg-reconfigure xserver-xorg" again and choose "advanced" monitor configuration that will ask you these refresh values.

Ok I tried some and will try your other advices.

Yes I tried to select vesa. But it didn't change anything at first. But afterwards I selected both 1024x786 and 800x600. Then the default screen resolution changed to 800x600 (this is a progress) and the options are now: 640x480 and 800x600.

yes I can try kanotix. But what is it? Is it an application that I can install using Synaptic?

Thanks for all your interest.

Kanotix is a live-cd, just like Knoppix.

There's also a tool, called "xdebconfigurator", that's supposed to help in X configuration and you can install it using Synaptic.

After installing xdebconfigurator, you can type "su" to become the root user and then type "xdebconfigurator -x". The whole output of that command probably won't fit to one screen but you can scroll to the previous screen by pressing the Shift and the PageUp keys simultaneously.

Then you can switch to another virtual terminal by pressing the Alt and the F2 keys simultaneously. Then log in, "su" to root and type "dpkg-reconfigure xserver-xorg".

You can switch between virtual terminals with "Alt-F1" and "Alt-F2" and apply the xdebconfigurator output in "dpkg-reconfigure xserver-xorg".

Or you can download Kanotix, burn it to cdrom, use it as live-cd and take the Xorg values you need from there, like I suggested in my earlier post. Whatever seems more convenient to you. However, I think that Kanotix might give you more reliable info because it has pretty good hardware autoprobe tools.

both vesa driver and xdebconfigurator used together.

Solved my problem.

I selected 1152X852 like resolution (I don't remeber exactly) with the classic three (1024x768 800x600 640x480) and the default was 1024x768@70Hz

But xdebconfigurator not enough all by itself. It wasn't a solution in my first attempts.

Thank you all!!!

If we could give you a perfect solution every time, it wouldn't be nearly as much fun. Advice is intended to get you on the right track. Glad it worked.

thought you might like this http://tuxmobil.org/toshiba.html. There are some debian installs on your lappy with XF86Config-4 files. Good luck.

Hi, I am running debian too and having a similar problem. I am trying to reconfigure the xserver so i can get a higher resolution but i am still stuck w/ 800x600. I managed to install xdebconfigurator but i dont have the xserver-xorg thing installed. I tried to apt-cache to it but it returns me nothing, what is the exact package's name so i can look for it?

when i try to use it this is the msg i get:
/usr/sbin/dpkg-reconfigure: xserver-xorg is not installed

Thanks for any help,

Debian stable doesn't have Xorg, it uses the XFree86 version of X Window System. Try "dpkg-reconfigure xserver-xfree86" instead.

Does pkg read-edid(apt-get install read-edid) work for lappy screens too to help xdebconfigurator?
One user with same lappy used HorizSync 28-50 and VertRefresh 43-75 with default depth 16 with vesa driver too.

Thanks guys. The option of dkpg-reconfigure xserver-xfree86 worked for me. But only w/ the vesa driver i could support 24 bits colour. Now i am going for my audio system. Thanks veru much for your help!

Should be worth a try, I think. If you're not happy with the results, you can always run "dpkg-reconfigure xserver-xfree86" (or "dpkg-reconfigure xserver-xorg") again to change the settings.

In theory, you should be able to get a decent Xserver configuration if you just run as root "xdebconfigurator && dexconf". (xdebconfigurator auto-probes your display hardware and writes the probed info to debconf's database; dexconf writes the debconf database info to the Xserver config file.) But in practice this doesn't always work.

EDIT:
Personally, I usually first run "xdebconfigurator && dexconf" and then edit the Xserver config file manually.

I don't install local font server, so I comment out the "unix/:7100" fontpath. On the other hand, I install msttcorefonts and x-ttcidfont-conf, so I add the fontpath "/var/lib/defoma/x-ttcidfont-conf.d/dirs/TrueType" on top of other fontpaths. (Later on, I run "dpkg-reconfigure libpango1.0-common", "dpkg-reconfigure fontconfig" and "fc-cache -fv".)

To get the mouse wheel working, I add the option "ZAxisMapping" "4 5" and change the mouse protocol to "ImPS/2" (because that's the correct protocol for my mouse although xdebconfigurator thinks it's PS/2). I also change the HorizSync and VertRefresh ranges to what the monitor's manufacturer recommends. I have one system that has nvidia card and the binary driver needs a modeline in xorg.conf that I get with xvidtune.

Here is the Linux Documentation Project's HOWTO that's supposed to be obsoleted by the new features in Xserver but it's still good info for troubleshooting when your display refuses to work as expected: http://tldp.org/HOWTO/XFree86-Video-Timings-HOWTO/
