Fn F7 - switch to vga port does not work under X

Hi everybody,

my problem: Fn F7 - switch to vga port does not work under X

at first the HW I am using: a IBM Thinkpad R50p with a FireGL ( lspci output: VGA compatible controller: ATI Technologies Inc M10 NT [FireGL Mobility T2] )
My current SW:
->Gentoo Linux, gentoo-dev-sources 2.6.9
-> xorg-x11-6.8.0-r1, my video driver is the standard video driver from xorg for ati
Identifier "Card0"
Driver "ati"
VendorName "ATI Technologies Inc"
BoardName "Unknown Board"
BusID "PCI:1:0:0"

Because i need to connect my laptop to an external monitor or a beamer, i need to use the vga port. Under the console, switching with Fn F7 works fine ( only laptop, both laptop and monitor, only monitor -> everthing works fine). As soon as i switch to X, the keys Fn F7 does not work any more. If I connect a monitor, the picture is directly shown on the external monitor without hitting the keys. But the picture flickers a lot, so its not usable. Any further hit of the keys has no impact. Any ideas ? perhaps some options in the xorg-config file ? I searched for quite a while, but didn't find a solution.

thx :idea:

I don't think the problem is related to virtual terminals. The "fn" key is specific to laptops. If it's an IBM system, you may need extra software to enable the VGA port, I've forgotten the name of it, but it probably wouldn't be the same as your system needs, since my video chip was an S3. Sorry I can't be more helpful

hi,

thanks for your hints.
i still think its a problem with the virtual terminals because on the console everything works fine with switching to the vga port.
The option "DontVTSwitch" i already tried. It did not help.
pressing press [ctrl] + [alt] + [F7] also did not work.

any further ideas ??

thx andrew

The console may work because of the resolution and refresh rate it uses. Are you using a framebuffer?

The software I needed was necessary if I wanted to use the VGA port for graphics mode, text came naturally to the system, for some reason. It also enabled the composite video-out port.

You could try starting X in a lower resolution to see if the external monitor works better...
