View Full Version : [SOLVED] dpkg-reconfigure xserver-xorg does nothing - Help please
January 14th, 2010, 06:59 AM
I need a video driver for SIS M760GX for an ACER Aspire 5000 laptop.
Everywhere I've looked it says to run
sudo dpkg-reconfigure xserver-xorg
Supposedly, this is supposed to open a window where I can change settings. However it does nothing and just returns me to the prompt.

What Ubuntu version do you have installed?
January 14th, 2010, 10:00 PM
I had 9.10 2.6.28-11 I didn't work on that one
Now I have 9.10 2.6.31-16 And it still does not work.
Help please. I can't use Ubuntu w/o fixing my video problem. It's usable, but the flickering screen and like 16 colors gives me migraines to look at.

I assume you have looked in System --> Administration --> Hardware Drivers to see if there is a third party driver for your display adapter. And, I assume you have tried the System --> Preferences --> Display panel to fix your resolution. Post to the forum the output of
sudo lshw -C display

In Hardware Drivers there is nothing except a Wi-Fi driver showing. Display preferences, the monitor is not detected. I can't change anything except the resolution which does not help. I still have like 16 colors, there are weird vertical lines, and what looks like snow or some kind of interference on the display.

The video adapter is listed as "unclaimed", meaning there is no specific driver for it. Therefore, it will be used in plain VGA mode, with low resolution. I think the driver is named "sis". The Ubuntu package for 9.10 is named xserver-xorg-video-sis (http://packages.ubuntu.com/karmic/xserver-xorg-video-sis), and can be installed using Synaptic package manager.
By the way, to see the xorg.conf file the command is:
cat /etc/X11/xorg.confLinux names are case sensitive.

I'll try that. TYVM!

From what I have read in other posts, there is apparently a problem with bandwidth on the SiS card and you will not be able to fix the flickering properly.
I have found that by removing the SiS driver will make it work a whole lot better. Use System-> Administration -> Synaptic Package Manager and search for SiS and remove it completely.
You will get rid of the vertical lines and constant flicker but you will still get some flicker from time to time (like a faulty monitor). This will go a long way to stopping your migraines but the only solution is to install a decent graphics card.

OK. I downloaded the package and it said it was already installed. So that didn't help. (Sorry for the long wait but I've been busy with school.)
So you can have a driver package installed, but the device still be unclaimed or not have a driver for it, right? In other words, the package does not work. Or is there something else I am missing? I posted xorg.cnf for you.
I guess I will try mount's advice posted in this thread, but he's saying to remove the driver. What driver. There is no driver for the unclaimed device according to you. Or I guess he means remove the package. I guess I will try that.
I guess I will try

Oh...and my graphic card works fine for any other OS. I am not playing games or using AutoCAD on this. Please don't tell me to buy anything when I don't need to. That's not why am I here.

I have the same problem trying to reconfigure the xserver. The command does nothing. I moved the disk to another computer with an on-board video and I am trying to reconfigure it. I have used the dpkg-reconfigure many times before with versions 7.04 and 8.10, but in 9.10 is doesn't work for me. I also do NOT have a /etc/X11/xorg.conf file. The on-board video is an Intel 82865G. I need to get the resolution to 1024 x 768, but the max allowable right now is 800 x 600.

yeah - I have the same problem as well on an HP Pavilion s7410n ...
stuck in 800x600 - but no flickering
dpkg-reconfigure xserver-xorg does nothing
no xorg.conf file on the machine either (ubuntu 9.10)

I hope im not hijacking this thread - but I just saw something interesting... I wanted to share with everyone...
I just migrated my friends little HP over from XP to ubuntu 9.10 - I also installed the edubuntu stack as well for her kids.
I explained to her, Im working on this crappy 800x600 thing. She said that's fine (for now) I need to get to my email - ill take it now, but if I learn anything she will do a reverse VNC and send me her remote desktop so I can work the issue remotely.
But before she took it home - I unplugged my 17" LG Flatron LCD screen - and plugged in an old Sony Trinitron 17 200GS CRT Tube to it and rebooted... ( I can provide specific model numbers if needed).
The machine came up in 1024x768 automatically ... hmmmm... Went into the settings and saw many resolutions which were exactly what I expect to see. testing all the way to 1280x1024... looked great...
I then swapped the CRT for the LCD - and everything looked even better'er... Thinking I had solved the problem... I then rebooted the box thie the LG LCD again - and Im back to 800x600 again. (also having 640x480 btw - who cares)
check this out ...
While the machine is running and logged in (in 800x600) - I swap the LCD for the SONY 200GS monitor... and WHAMMO the display settings app identifies the Sony monitor (puts the word SONY in the little pink box for me) - and gives me all the wonderful resolutions again...
PLEASE NOTE - I did NOT reboot, and I did NOT log out... I simply swapped the monitors.
I then put the LCD back - and all resolutions stay available to me ...
I dont know anything about how these monitors are polled for their capabilities - but obviously the old Sony CRT provides the correct info where as the LG LCD does not (for whatever reason).
I hope this might help someone else down the road.
