Thank you very much for you answer. I will explain the situation more.
The first of all here is some info about inputdump program
Environment:
Celeron 450 96 Mb memory Matrox G100. Linux Red Hat 6.0 usual installation
without kernel recompiling.
Matroxfb is loaded as module in /etc/rc.d/localinit.d
instmod matroxfb
fbset xga16 -a
where xga16 is my setting for 1024x768 16bit
Svgalib is not intalled.
when I start under root I've got normal behavior and error output:
Under usual user I've got error output:
display-fbdev: ioctl(VT_GETSTATE) failed: Invalid argument
L/vtswitch: open /dev/vc/8: No such file or directory
Linux-kbd: Couldn't open TTY: Device not configured
display-fbdev: Unable to open linux-kbd, trying stdin input.
Also gpm mouse is always on the screen.
when I run my program I've got stderr output:
display-fbdev: ioctl(VT_GETSTATE) failed: Invalid argument
L/vtswitch: open /dev/vc/8: No such file or directory
Linux-kbd: Couldn't open TTY: Device not configured
display-fbdev: Unable to open linux-kbd, trying stdin input.
1024x768.V1024x768.F2.D1x1.[C16/16]
My program draws some lines boxes over a screen within 10 sec. it stops
after.
If I do not touch any key or mouse there are no problems except one.
Sometimes I can see text cursor blinking in down part of the screen.
When I'm going to switch consoles my program is drawing over these consoles.
And also program completely loses parent console background.
When I ran inputdump using root I also had problems with loosing of
background. There is no problem with switching between consoles except that
one.
About vesafb. When I start Linux using vesafb on the same configuration I
can not run my program in F2 mode as well as I can not run GGI demo programs
in the same mode or using virtual screen.
Best regards, Dmitry

Weird. Never had this problem.

How many vidoe card do you have? Their is normally one video for all
virtual terminals. If you have more than one video card that uses fbdev
then you can use a utility called con2fb to map consoels to a particular
video card.

Starnge. Never had this problem. I switch all the time between Mesa-GGI
and my nice fbcon termninal.

Hum. These are fbcon bugs. More like console code bugs. I have sent this
to the fbdev list.

This is right. Fbcon allocates all the video memory. This enables nice
scrolling.

I believe with GGI you can allocate more than one frame when you set a
mode.

I never seen this before.

You shouldn't have to worry about this.LibGGI does this for you.

LibGGI has no cursor support as of yet. This falls under the area of
sprites but I haven't heard anything recently on this.
