Wide Screen with Core plus and Intel GM45
« on: October 28, 2014, 08:15:16 AM »
Hi,

I know this topic has been talked about a lot. I've googled and looked around in this forum.
But being a total newbie I couldn't get a working solution as of yet. So I desperately need a "not possible" confirmation or a solution.

I have a netbook with an Intel GM45 graphics chip supporting 1366x768.
My desktop resolution at the moment is 1024x768, so display is torn wide.

I've read about 915resolution. So I have it load onboot.
In .xsession i write:

(...)
915resolution 5d 1366 768 32
Xvesa -br -screen 1024x768x32 -shadow -2button -mouse /dev/input/mice,5 -nolisten tcp -I >/dev/null 2>&1 &
(...)

On reboot desktop comes up, but still torn wide.

Somewhere I've also read that 915resolution now supports Intel G45
Do I have any chance to get anywhere?

Thanks for your help.

Someone please correct me if I'm wrong but I don't think Xvesa knows how to produce wide screen display.  I've never been able to get it to work without distortion.

Try Xorg-7.7.tcz, possibly along with graphics-KERNEL.tcz

32 bit core4.7.7, Xprogs, Xorg-7.6, wbar, jwm  |  - Testing -
PPR, data persistence through filetool.sh          |  32 bit core 8.0 alpha 1
USB Flash drive, one partition, ext2, grub4dos  | Otherwise similar

The line
Xvesa -br -screen 1024x768x32 -shadow -2button -mouse /dev/input/mice,5 -nolisten tcp -I >/dev/null 2>&1 &
is NOT using the new mode.

Put the "915resolution 5d 1366 768 32" in /opt/bootlocal.sh.
Run xsetup and select the 1366x768 entry.
Then run startx.

Don't forget to run a backup to save your changes.

Thanks. This is what I did:

1. removed the 915resolution call from .xsession
2. removed the Xvesa call from .xsession
3. put the 915resolution call in /opt/bootlocal.sh
4. rebooted
5. prompt came (no desktop yet)
6. called xsetup: But no 1366x768 option available. Only 1024x768.
7. selected 1024x768
8. called xstart
9. desktop came, obviously no change.

btw
xsetup puts the line
Xvesa -br -screen 1024x768x32 -shadow -2button -mouse /dev/input/mice,5 -nolisten tcp -I >/dev/null 2>&1 &
into .xsession
So "not the new mode" as you said is done by xsetup.

Please keep helping!

If you want to avoid Xorg for some reason, graphics- and Xfbdev should use the native resolution.
The only barriers that can stop you are the ones you create yourself.

To avoid using 915resolution.tcz with my Intel 945GME, I have this in my syslinux.cfg:
Code: [Select]
UI vesamenu.c32
MENU RESOLUTION 1024 600
...
This makes the linux console using the proper resolution as well.
Download a copy and keep it handy: Core book ;)

@Misalf: Tried it, no luck.
@Curaga: graphics and Xfbdev finally worked out!

Thank you so much.
