My Daryna desktop looks pretty, fonts are anti-aliased and the fonts´ size and the laptop performance is c00l

But I'd like to set it up to 1280x1024@32 or @24.
1280x800 would be nice too...

I've searched the forum for '915' but threads are about enabling desktop effects I don't really need.

Any hint?

Thanx in advance

[Husse]

The 915 is OK but you need 915resolution, I could not see it
You can remove all the drivers for other video chips
This is Daryna main?
Post your xorg.conf

I think that should give you 1280x800 resolution... But be sure to backup xorg.conf FIRST!

[gabrielmenini]

Thanx for the tip, but didn't changed the resolution

[MagnusB]

Did you restart X after changing it?

[gabrielmenini]

You mean issuing CTRL+BACKSPACE ?

Yep..

[Husse]

Virtual 1024 768

Running in Virtualbox or VM ware?
I think you can remove the above line
My xorg.conf does not even have a "Section Display" and no resolutions listed
The way X is controlled has changed....

[gabrielmenini]

Husse,

Would you mind posting your xorg.conf file here?

[Husse]

Not at all, but I have nvidia
I remembered that some time ago a lot of people had this kind of problem and I also remembered a solution
The refresh rates of your monitor may be out of sync
Run xvidune in a terminal and click Cancel in the popup that pops up
In the terminal you now have the vertical and (above all) horizontal sync rates for your monitor
Use these in "Section Monitor"

...then restarted X with CTRL+BACKSPACE but the resolution remains the same and the tool XFCE4 provides for changing resolution doesn't list 1280x800 in the drop-down list...

The horizontal sync values are very low...
Put the 1280x800 modeline line on top. The first line becomes default

Well then don't - ask!
You are being helped....
I did not look at the modelines so I did not see that they were almost the same
Modelines should not have to be used, so I assumed you had gotten them from somewhere.....
Should have asked

[BlahBlah_X]

Ummm try this:

sudo apt-get install 915resolution

then, do man 915resolution for usage details. This tool should accurately change the resolution where xorg can't always.

Give it a shot, and post the results.

The display isn't wide screen so perhaps 1280x800 isn't the best choice.

[Husse]

We've tried to help you get 1280x800 which is a difficult resolution and now you say

The display isn't wide screen so perhaps 1280x800 isn't the best choice.

and state that 1280x1024 may be the best for you
Don't waist our time and patience

[gabrielmenini]

Don't waist our time and patience

Not wasting nobody's time since I've posted a lot of info here.

Maybe 1280x1024 is what I need, but I didn't know if the display supported it (915resolution tells me now that it does) and 1280x800 didn't sound as a «difficult resolution» for me.

Take it easy, man.

I am learning the same way you were learning maybe decades or minutes ago.
I do appreciate your patience and generosity.

[MagnusB]

What Husse probably mean that if the panel do not support 1280x800 resolution, and you failed to mention it was not a widescreen means we have wasted our energy trying to solve a problem that has no possible solution. I always note, from the OEM install, the resolution, since in most cases it is set to max there. So my maximum resolution is 1280x800 and what fits my screen perfect.
Try:

Code: Select all

915resolution 1280 1024

Might require sudo..

[gabrielmenini]

OK, here are the info I can provide:

• It's not a wide screen display, it's the Dell Latitude D510.
• The propietary driver for WindowsXP used to put 1024x768 as max resolution.
• LinuxMint "Daryna" based on Ubuntu 7.10 and using XFCE4 as desktop manager is running now at 1024x768, the default resolution after install.
• Tweaking the x.org file for 1280x1024 from a TTY and then issuing xinit starts the X server but the screen seems to flash twice before showing the xterm (maybe it's falling into a lower res?)
• 915resolution echoes the following, but I don't know if it sets anything somewhere...
