Hi. I'd appreciate if anyone there using virtual terminals (vt's) on cards (at least two, different or not) using framebuffer (fb), can confirm this bug: output to these vt's finishes in one of them. I use: -SuSE 7.0 with kernel 2.4.7. -Primary: S3 AGP (no fb). -Secondary: Matrox Mystique 220 PCI (using fb, module matroxfb_base). -Other: clone Hercules MDA ISA (using module mdacon (text), and module hgafb (fb)). Kernel configuration: CONFIG_FB=y CONFIG_DUMMY_CONSOLE=y CONFIG_FB_HGA=m CONFIG_VIDEO_SELECT=y CONFIG_FB_MATROX=m CONFIG_FB_MATROX_MYSTIQUE=y CONFIG_FBCON_HGA=m CONFIG_MDA_CONSOLE=m This is framebuffer, Matrox and Hercules stuff. On /etc/inittab: 8:123:respawn:/sbin/mingetty tty8 9:123:respawn:/sbin/mingetty tty9 10:123:respawn:/sbin/mingetty tty10 11:123:respawn:/sbin/mingetty tty11 12:123:respawn:/sbin/mingetty tty12 This defines vt's tty8 to tty11 (as common tt1 to tty6, tty7 for X), and also tty12 which will be used by mdacon (see below). On /etc/lilo.conf: append ="... video=vc:8-11" This says that fb vt's will be at tty8 to tty11; its use is as normal vt's (Alt+F8 to Alt+F11). On /etc/modules.conf: options mdacon mda_first_vc=12 mda_last_vc=12 options matroxfb_base dev=0 vesa=0x10C novga To assign vt's to modules/cards: modprobe hgafb con2fb /dev/fb0 /dev/tty10 con2fb /dev/fb0 /dev/tty11 modprobe matroxfb_base con2fb /dev/fb1 /dev/tty8 con2fb /dev/fb1 /dev/tty9 This assigns tty10-tty11 to Hercules, and tty8-tty9 to Matrox. The bug is that output to Hercules (Alt+F10, Alt+F11) finishes (undecipherable) at Matrox, no matter if changing in any way or in any order, or separate, those commands. (With just the first three lines, as supposed, with no Matrox involvement, things work). Matrox vt's (Alt+F8, Alt+F9) work well. Trying the same with module mdacon (Alt+F12, text 25 lines vt, no fb) instead of hgafb the same happens: output to Hercules goes to Matrox. Trying the same with module mdacon and hgafb (not involving Matrox) the result is equivalent: output to mdacon (Alt+F12, text) seems treated by hgafb, and only dots are seen. Output to hfafb is normal. The same, and worse, if using the three modules at the time. So could be: -there is some configuration I am missing; -similar bug in both hgafb and mdacon, not knowing where their output should go; -a general bug in Linux vt switching. I know that monochrome Hercules are very old, and hardly will be used. But perhaps someone with two or three graphic cards, and using fb vt's, can try. Anyone can reproduce this? Any suggestion?
