Yes: # ls /dev/vcs* /dev/vcs /dev/vcs2 /dev/vcs4 /dev/vcsa1 /dev/vcsa3 /dev/vcs1 /dev/vcs3 /dev/vcsa /dev/vcsa2 /dev/vcsa4 Looking at the code, the vc_screen.c code seems to create those devices unconditionally. > > And what does this say? > grep . /sys/class/tty/tty0/active /sys/class/tty/console/active # grep . /sys/class/tty/tty0/active /sys/class/tty/console/active /sys/class/tty/tty0/active:tty1 /sys/class/tty/console/active:ttyS0 vcs1 has, roughly: early console in decompress_kernel Decompressing Linux... Parsing ELF... done. Booting the kernel. Now I'm wondering how that buffer came to be. In any event, some tracing of the code suggests that I have vga_video_type == VIDEO_TYPE_CGA, and that fails "if (vga_video_type < VIDEO_TYPE_EGAM)" in vgacon_font_set. Indeed, /proc/ioports has: 03d4-03d5 : cga and dmesg says: [ 0.000000] Console: colour *CGA 80x25 I don't see this information in sysfs anywhere. Perhaps checking for an active console and detecting -EINVAL from vgacon_font_get would work. /proc/fb is empty on this VM, so maybe that would help. Grr, this stuff is really old and crufty. The offending qemu command line args appear to be -vga none -display none. I assume I have "CGA" because it's the fallback case in vgacon.c if nothing matches. --Andy _______________________________________________ systemd-devel mailing list systemd-devel@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/systemd-devel
