problems setting 1280x800 resolution


originally i had a problem installing mandrake 10.1 on my laptop becuase when i chose the settings that i chose, althought the correct settings, did not display the screen properly. so then i tried 1024x768 and it worked. my screen, however, is 1280x800. i have a intel 855 graphics card and am using a dell 700m. is not being able to set the resolution to 1280x800 a typical problem? are there any solutions? please help! Thanks...

Make sure you have set up your correct monitor in the MCC. I had this problem before with my Dell. It wasn't displaying widescreen like it was supposed to. So make sure you have your monitor model set.

What do you mean that "it did not display properly".

A bit more explanation would be helpful.

Try being quite a bit more descriptive so we can have a clue.

I am having the exact same problem....same laptop.....when you try to run it in 1280x800. You know when you set any monitor to a lower resolution ie. 640x480 everything looks huge? it does that only on a larger scale....its like 12x34 lol....you can only see the top of the dialog box asking you if you want to keep these settings....quite frustrating. I hope that cleared some things up with describing the problem.

Usually the virtual screen appears due to one of two things...

a) You have correctly set things up, but other modelines occur first in the X configuration file causing the initial display to default to some other res.

When this occurs hit CTRL-ALT-[+] or CTRL-ALT-[-] minus to toggle through the available modes.

b) Even though you are correctly specifying the resolution, the hardware does not report, support or provide adecuate resources to give you the res you specified and the system drops into virtual mode.

This may be due to

1 - Inccorect identification by the driver of available VRAM
2 - NO VRAM present (as in a shared memory system, such as yours)
3 - The driver does not support your requested configuration
4 - Wrong driver

You may have to explicitly specify the amount of VRAM available to the system directly.

Note: that shared memory systems as highly problematic as they are very akin to Winmodems in the way they function.

How much do you have?

Most Intel Motherboard based video have NONE! That is no dedicated video ram.

Rather they use a shared memory scheme.

The amount of VRAM is usually passed back to the driver via a parameter in the Xorg.conf or XFconfig file in /etc/X11

I still can't figure this blasted thing out. is their any other place i can look to find out how much vram the computer "thinks" is there? i tried looking in the etc/X11 directory for the XFconfig but couldnt find it. i did, however, find the Xorg.conf but i didnt see anything in reference to vram. also, i found some drivers for the 855 graphics controller, i think, http://downloadfinder.intel.com/scri...2&DwnldID=8203 . so i go into the shell and unzip the tarball thingy with the command
"tar xzvf i915graphics.tar.gz" without the quotes. after they are unpacked i log into root and go to the directory where i unzipped it to try and run the instal "./install.sh" but i get the error message
"Could not locate some required utilities: ed"
"aborting"
I tried reading the readme on the website but it proved to not be of much use. any help would be appriciated


Here is a complete copy of my Xorg.conf file. if there is anything i should change please let me know.....thanks so much!

Eh, your are missing the point.

If you have an integrated chipset, you may have NO vram, which will create a problem for the driver.

So again, how much actual VRAM -DOES- your system have?

Don't rely on Linux for the answer to this.


Also all of your screen definitions are for virtual displays.

Did you kill the display manager and run XFdrake to set things up?

From the output of the configuration file it appears that you may not have, though I am working with limited information.

Also your system lists TWO display devices. How many do you actually have?

E.g. it shows "screen1" and "screen2".

Also

You have defined a modeline for your desired 1280x800 resolution, but where is the corresponding "Display" section?

E.G.


Subsection "Display"
Depth 8
Virtual 1280 800
EndSubsection

Subsection "Display"
Depth 15
Virtual 1280 800
EndSubsection

Subsection "Display"
Depth 16
Virtual 1280 800
EndSubsection

Subsection "Display"
Depth 24
Virtual 1280 800
EndSubsection
EndSection


etc...
