MiniMe KDE 11.07 won't retain 1366x768 on Intel Mobile 4 setup (2 Work-Arounds)

[utu]

Greetings to all

I have just installed MineMe KDE 11.07to 4 Gb SanDisk with otherwise
flawless results.  But, I can't get my new system to retain 1366x768
resolution on reboot.
I do: Configure Desktop/Display & Monitor/Size 1366x768 & save as
default.  Seems like that should work, but that doesn't hold.

If, as an alternative, I write over xorg.conf with one I know works,
things also get reset to 1024x768 on boot.

lspci | grep -i vga (as root) gives:
00:02.0 VGA compatible controller: Intel Corporation Mobile 4 Series\
Chipset Integrated Graphics Controller (rev 07)

I can live with 1024x768, but it seems like something here is amiss.
It looks like the original hardware detection gets things wrong, and
furthermore, doesn't respond to a requested default change.

I am interested in a work-around for this minor annoyance.

Have you tried using

PCC (Configure Your Computer)  >> Hardware >> Configure Video Card >

and setting it there?

May need to restart your desktop.

@ menotu

Thanks for your response.
I have tried PCC>>Hardware>>Config Card as well, with the same non-result.

FWIW. lsmod says I'm using i915 driver.

 Try PCC>>Hardware>>Configure Video Card, but set the resolution to 'Automatic'. This usually works for me.

The problem I usually run into is KDE setting the resolution to what it wants instead of what I specify in PCC. Setting the resolution to 'Automatic' in PCC always fixes this for me.

@ SpinheadMickey

Thanks for your suggestions as well.
I am still having the same problem here.

I have tried coming at it from 'Configure Hardware' rather than 'Configure Desktop', and tried a lot of combinations of Monitor and Resolution.
I've tried full reboots and control-alt-backspaces to the same end.

In every case, after a full reboot, the splash screen comes up 1366x768,
but as soon as things go to X, we're back to 1024x768.

utu try moving /etc/X11/xorg.conf out of the folder and boot without one and see if that works or not. If not then move the xorg.conf file back to the /etc/X11 folder.

Thanks for your suggestion, Texstar.

No change here.
System replaced a 1,976 byte file with another 1,976 bytes.

FWIW neither the original or the current xorg.conf nor xorg.conf.old have
any mention of a 1366 resolution anywhere.

I have been able to operate with an xorg.conf from another system,
a file several times larger, but it too gets replaced at boot with a 1,976 byte xorg.conf, with the 1366x good news during the frambebuffer(?) period but
then back to 1024x when X comes on.

Thanks again for your concern.

[Texstar]

When you into the Configure your Desktop -> Display and Monitor. Is the 1366x768 resolution available to you?

If not then you might try this.

Open the Configure your Computer
Configure Video
Set your resolution to 1366x768
Save and exit.

Open a terminal console
su to root
type chattr +i /etc/X11/xorg.conf

This will prevent xorg.conf from being able to be modified.

To reverse the above setting:

chattr -i /etc/X11/xorg.conf

Thanks Texstar, that worked.

I'm impressed, very.

Texstar, I ran across this in my syslog; repeated on every boot-up.

Maybe this gives a hint as to what was causing my problem:

Jul 18 19:06:00 localhost klogd: fb: conflicting fb hw usage inteldrmfb vs VESA VGA - removing generic driver

The 'chattr' work-around solves my complaint, but may not keep similar complaints from
coming your way.

Best regards.

On a related matter:

I was surprised to find the chattr approach would not solve this
same problem for me in the 11.06 LXDE version of PCLinuxOS LiveUSB.

I found a different (adequate for me) solution for that situation.
That's presented near the end to the thread at:

Cheers

Here's another solution that works for PCLinuxOS LXDE-mini 11.06:

1. mv xorg.conf xorg.conf.orig
2. control-alt-backspace
3. voila! Look, Ma; correct resolution and NO xorg.conf at all.

Found this at

I expect this may also work for the KDE version.
