[Pavel Kysilka]

   Hi,

i have ATI Rage128 AGP card.
I was testing framebuffer. Switching resolution in one console working.
Switching all consoles do not working. Only aktual console is switched.

modprobe aty128fb
chvt 1
fbset

mode "640x480-60"
    # D: 25.171 MHz, H: 31.463 kHz, V: 59.930 Hz
    geometry 640 480 640 480 8
    timings 39729 48 16 33 10 96 2
    rgba 8/0,8/0,8/0,0/0
endmode

fbset -a 800x600-100 -depth 32

mode "800x600-100"
    # D: 67.490 MHz, H: 62.491 kHz, V: 99.985 Hz
    geometry 800 600 800 600 32
    timings 14817 216 0 14 7 64 4
    hsync high
    vsync high
    accel true
    rgba 8/16,8/8,8/0,8/24
endmode

chvt 2
fbset

mode "640x480-60"
    # D: 25.171 MHz, H: 31.463 kHz, V: 59.930 Hz
    geometry 640 480 640 480 8
    timings 39729 48 16 33 10 96 2

endmode

Error is independent with color depth end resolution. intelfb and matroxfb
driver working with this feature correctly.

Can you insert debugging printk's in linux/drivers/video/fbmem.c:
fb_set_var()? It must reach this statement block with the FB_ACTIVATE_ALL
flag intact in order for setting all consoles to work:

			if (!err && (flags & FBINFO_MISC_USEREVENT)) {
				struct fb_event event;
				int evnt = (var->activate & FB_ACTIVATE_ALL) ?
					FB_EVENT_MODE_CHANGE_ALL :
					FB_EVENT_MODE_CHANGE;

				info->flags &= ~FBINFO_MISC_USEREVENT;
				event.info = info;
				blocking_notifier_call_chain(&fb_notifier_list,
						evnt, &event);
			}
