Hi All,

I am really stuck on this, I have upgraded to fiesty, previous versions had no problem with the display. Now I am stuck at 800 x 600 instead of 1024 x 768.

The old version (pre upgrade) was preserved, if I restore this it makes no difference.

I have tried

sudo dpkg-reconfigure -phigh xserver-xorg

this removes all resolutions except 1024x768 and subsequently prevents me from running the GUI... I have to replace xorg.conf in safe mode to restart the Gnome.

I cannot see anything wrong with xorg.conf, seems to have picked up my screen ok which is described here:

ciao.co.uk/Fujitsu_Siemens_AMILO_K_7600__5319778#productdetail

My xorg.conf looks like:

# sudo dpkg-reconfigure -phigh xserver-xorg

Ok finally got what some of you were on about regards the vertical and horiz resolution, inserted this and all went well:

Section "Monitor"
Identifier "Generic Monitor"
HorizSync 28-51
VertRefresh 43-61
Option "DPMS"
EndSection


I noticed that

sudo dpkg-reconfigure -phigh xserver-xorg

inserted the horiz and vert rates, so I pasted those into my existing file. I increased the upper value of vert to 61 which was the value I could see in my screen resolution dialogue box, I also used this

http://www.bohne-lang.de/spec/linux/modeline/

which suggested at 60hz the upper limit should be 60.8, not sure if that is relevant.

Anyway thanks to previous posters for all the info you left....

i want to increase the resolution but
unable to do as system-->preference-->screen resolution
displays 1024*764 as the max resolution available and refresh rate 85Hz

here's my xorg.conf file
Code:
# /etc/X11/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.
#
# Edit this file with caution, and see the xorg.conf(5) manual page.
# (Type "man xorg.conf" at the shell prompt.)
#
# This file is automatically updated on xserver-xorg package upgrades *only*
# if it has not been modified since the last upgrade of the xserver-xorg
# package.
#
# If you have edited this file but would like it to be automatically updated
# again, run the following command:
#   sudo dpkg-reconfigure -phigh xserver-xorg

The i810 driver does not go over 1024x768. I assume you have the video integrated on your MB. Please post the chipset that is used on your motherboard and the make of model of your monitor.

There is a tool called 915resolution that might help for certain Intel chipsets; you can find info here. Not 100% sure but I think it's in the Ubuntu repositories (you might have to enable universe or multiverse in synaptic).

hi

thanks for the reply
but i found the solution
i ran a command "sudo dpkg-reconfigure -phigh xserver-xorg"

By selecting i810 from the list, then checking all the checkbox from minimum resolution to 1280x1024, and then restarting the computer gave me the max. resolution i wanted.

Thanks again
varun

So you say that the i810 driver supports more than 1024x768? Never knew that; sorry for the incorrect information.

lspci -v displays this

00:02.0 VGA compatible controller: Intel Corporation 82Q963/Q965 Integrated Graphics Controller (rev 02) (prog-if 00 [VGA])

I think graphics card has 256M of memory thats why i can have a resolution of 1280x1024

The 256M has no influence in this case (you can still get 1280x1024 with something like 8MB video memory); I have always been under the impression that it was a driver limitation. The solution is to install 915resolution, but it does not seem to be necessary in your setup.

A variant on the low resolution problem!!!

OK Guys...

I have just bought a new computer (Intel 946) and convinced my children
(and my wife!!!) that it would be better to install ubuntu than
windows. I told them about security issues, plus the fact that
windows is full of bugs and patches...

Of course, the first thing that happened was that I could not
get the 1440x900 resolution that the wide screen recommended
(AOC, 19 inches)!

So I went to the forums... and I tried EVERYTHING!!!!!
The ``915resolution'', the ``xserver-xorg-video-intel'' package,
the ``dpkg-reconfigure -phigh xserver-xorg'' with ``intel'' and with
``vesa'' options... I have tweaked my xorg.conf file...
and NOTHING works!!!!!!!!!!!!!!!!!!!!!!

Here is what happens:

I do get the 1440x900 option in SYSTEM>PREFERENCES>SCREEN RESOLUTION
but when I apply it, the display only occupies 4/5 of the screen.
If, further, I accept that resolution and then try an ``unsupported
resolution'' the screen goes black for the 15 second trial period and
returns perfect!!!!!!!! (It has the correct resolution and uses all
of the screen!)

Now, I am sure there must be a way of bypassing all this rigamarole
and getting the bloody thing to work properly from the beginning!!!!!!!!!

Please don't let me fall back into windows...

Thanks

Nan

Hi Varun...

Thanks for the suggestion... I've been to that thread, I have tried the Modelines
and the Displaysize, but to no avail... The problem is not getting the 1440x900
resolution (by now I can do that in tons of ways!), the problem is that when I
ask the computer to use this resolution, it only uses part of the screen...
When I then attempt a not supported resolution from this warped 1440x900 screen,
which leads to a black screen, and return to 1440x900, then I get a nice complete
screen display...

Hi lal1,

I am as sure as I can be that the issue will lie in xorg.conf.
I know you have tweaked this already, why dont you try posting parts of xorg.conf in relevant forum threads (like this one) and ask for suggestions that way.

It would be a shame if you were to give up on it having come so far, IMO Ubuntu is worth the effort & once you are past this glitch you should find it plain sailing....
