https://bugzilla.novell.com/show_bug.cgi?id=259577 Summary: /etc/rc.d/kbd corrupts video when specified vga= mode is native 132 column Product: openSUSE 10.3 Version: Alpha 2plus Platform: PC OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Basesystem AssignedTo: bnc-team-screening@forge.provo.novell.com ReportedBy: mrmazda@ij.net QAContact: qa@suse.de http://bugzilla.kernel.org/show_bug.cgi?id=7513 asserts that "userspace" is the problem and not the kernel, which is why I'm filing this here. Also as noted in 7513, this is far from new behavior, and is not unique to any SUSE version. When a 132 column graphics card native vga mode is specified to the kernel, either directly or with ask, console video initializes at the specified mode. During init, the number of lines output is changed from the correct number to some lesser number, or to the correct number but with insufficient scanlines allotted to each line for full character height to be displayed. For example, I just installed factory fresh via http, with graphical YaST, and on first boot typed in vga=ask, following which I entered scan, and then selected mode 030A, which is 132X43 on mga. Video properly initialized in 132x43, but as init proceded a shift was made to ~24 lines. YaST then failed to come up in graphical mode. In text mode, YaST assumed the correct number of lines, 43, with the result that focus, descriptive text, and entry fields were out of sync, unable to fit on the supposed 43 line screen that was only 24 lines long. This makes using YaST extremely difficult, guessing via some familiarity when the focus is at some appropriate point and what action, enter or tab or arrow or other, should follow to achieve desired result. This unwieldy YaST behavior is similar to that of other ncurses utilities, like SAX, when run on a fully installed and configured system. As noted in 7513 kernel bug, many other graphics cards than mga exhibit similarly corrupt behavior when native 132 column modes are specified to the kernel. Doing as suggested in that bug's comment 7 (removing execute from /etc/rc.d/kbd) avoids the problem. Matrox, among others, supports no better than 800x600 (e.g. 0x314) framebuffer video, which is the reason to want native mode support of more console lines and rows than 100x37 and why this needs to be fixed. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

This is also reproducable in 80x43 mode. The important information is the size of the chacracter cell and the CONSOLE_FONT setting in /etc/sysconfig/console. If an 800x600 resolution is chosen for 43 lines, then the character cell must be less than 14 pixels in height. A standard 9x16 font wont fit. The size of the character cell is never computed or queried during startup. So /etc/sysconfig/console only knows what was true before reboot. kbd has only one choice: use the entry in /etc/sysconfig/console. This could be improved a) by rewriting entries in /etc/sysconfig/console before kbd is called b) by providing several fonts for several typical character cells. and probing for the current cell size. c) improved by rejecting to load a font with the wrong cell size. Hmmm. a) is horrible. b) requires some rewrite of the code that handles /etc/sysconfig/console Quite complex, and not easy to test or maintain. c) would be a nice kernel feature. This is a fallback to kernel's default font. Not perfect (possibly wrong locale), but better than nothing. I do not believe I could 'fix' anything inside the kbd script today. Werner any other proposals? I'll close as wontfix for now. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

An environment variable belongs to a process, and a tty size belongs to a tty. When you open /dev/console, you get the _same_ tty as if you open /dev/tty1. And COLUMNS/LINES environment variables do get exported to the init scripts, and do not get updated when the VT is resized due to the new font. I dug a bit more into them, and it seems that the problem is somewhere in rc_status (probably the pretty-printer). I'm wondering: aren't you able to reproduce the problem by setting an 8x8 font in /etc/sysconfig/console ? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

After the system is up and the virtual consoles are established no COLUMNS nor LINES is set, simply do ps aex | grep mingetty | grep COLUMNS to see this. Only on a serial system console the kernel actual does not know which size the console has. Then COLUMNS is set to 80 and LINES is set to 24. There is no method to determine the correct size of a serial terminal that is that the ioctl TIOCGWINSZ used by e.g. stty fails. At least I'm not able to reproduce your problem on a normal vga console as I always set 8x8alt on all none frame buffer system I use (most test system around here). It works as it should. It would be interesting to know if stty size is able to report the correct size of your console device during boot. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

It's _during_ the boot process that the screen gets resized. As the beginning of the bug report says, the bug is encountered with other vga modes than the standard one. Try vga=scan and check the various modes that your card allows. In my tests, stty size was always correct, and that makes sense since the values come from the kernel. LINES/COLUMNS given to boot scripts, however, get stuck at the original text resolution with the 8x16 font. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I'm only interested in values that stty reports *during* boot on /dev/console before starting blogd. This because I'm suprised to see 24 lines in your inital report known from xterms used for a serial line whereas the standard is 25 lines for the 8x16 font. This may only happen is LINES is unset and stty fails to report the terminal size (compare with /etc/rc.status). For a test you may also replace in /etc/rc.status the lines if test -z "$LINES" -o -z "$COLUMNS" ; then eval `exec 3<&1; stty size <&3 2>/dev/null | (read L C; \ echo LINES=${L:-24} COLUMNS=${C:-80})` fi test $LINES -eq 0 && LINES=24 test $COLUMNS -eq 0 && COLUMNS=80 export LINES COLUMNS with function rc_lc () { if test -n "$REDIRECT" ; then set -- $(stty size < "$REDIRECT") else set -- $(stty size) fi LINES=$1 COLUMNS=$2 test $LINES -eq 0 && LINES=24 test $COLUMNS -eq 0 && COLUMNS=80 export LINES COLUMNS } rc_lc to see if this makes a difference during boot.

But then seemingly on the next call to rc_status, the text screen is resized by half, leaving the bottom half of the screen blank. The original report said ~24 lines, which is half of the 43 lines which were obtained by the 8x8 font. Note that these values depend on the particular VGA/VESA mode that was set, but it seems to be always cut back by half by the second resize. I was talking about the stty values during boot too, but in my case (default installation) setfont is run in rc3, so after blogd is started. They are always valid (e.g. 25 lines before setfont and after 50 setfont). The change do not seem to help :/. However, it is probably worth noting that deactivating parallel boot RUN_PARALLEL=no in /etc/sysconfig/boot, the problem disappears (even without LINES/COLUMNS change). Putting a sleep 15 in the kbd script fixes it as well. I gather then that it's not a problem of LINES/COLUMNS (sorry for the noise...), but e.g. some ncurses program that runs in parallel and restores the tty state. I tried disabling various /etc/init.d scripts, and it appears that running just S05network triggers the bug, but also running all others except that one triggers the bug too. Does startpar do stuff with the tty? -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

You may try to add `kbd' to the `<interactive>' line within /etc/insserv.conf and run `insserv' afterwards. This should help to run kbd as a single process. AFAIK the startpar code uses getpt() together with fork() to start a process within its own pty and exports the previous readed values of the termios with the output mode cleared from the OPOST bit and the screen size to the new pty.

I also tried mga with 0x30a on same system and got 43 rows that stayed 43 rows, but also only used about 3/4 of the vertical screen space to do it. However, the boots with attachment 221985 in place and using 0x122 or 0x30a take much longer than normal, and leave me with no (e100) eth0. Restoring the original startpar restores eth0 function and boot speed. What could be that relationship? BIOS shows eth0 shares IRQ7 with AGP, but /proc/interrupts shows eth0 on INT16, AGP using no interrupt, and INT7 not used. Only vga=, root=, noresume, splash= & 3 on cmdline.

What's about attachment #221749 [details] or the original startpar? Does this slow down happen with all of them that is that the real reason is not startpar but your kernel update?

I don't understand your language well enough to know if this might be a complete answer: Using either attachment, boot is slowed, and eth0 does not exist, regardless of framebuffer mode. Using the 11.0rc1 startpar, boot is normal speed and eth0 works, regardless of framebuffer mode. The same behavior applies with kernel-pae-2.6.25.4-6 & kernel-pae-2.6.25.4-10, and on both P4 and Sempron 32 bit systems. Once either attached startpar has been loaded, switching to runlevel 1 is required to unlock it so that it can be replaced with another. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

The one I use most has broken or dead DDC. I tried a few others from http://tldp.org/HOWTO/Framebuffer-HOWTO-5.html too. All on MGA: 0x163 produces black screen 0x301 is 80x30 0x303 is 100x37 0x305 & 3x317 are 128X48 0x307 & 0x31A are more than 128 X more than 48, too tiny for me to count without eyestrain or magnifying glass 0x30A MGA looks like 132x43 using glyphs that look like would fit 132x60 Of course, none of those I mentioned today but 0x30A, 0x121 & 0x122 are proprietary modes. Framebuffer has been fine all along (except in Ubuntu), as long as supported by the video chip. MGA with older BIOS only supports 800x600 framebuffer, and old Intel (810, 815) no framebuffer, which is why 30A and the Intel proprietary (native) mode users want this bug fixed. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I don't know what normally writes to /etc/sysconfig/console. I don't recall ever changing one myself. The one I'm looking at now has CONSOLE_FONT="lat9x-16.psfu", and the file was last written yesterday at 03:04. That time, similar to many others in /etc/sysconfig, was probably when the machine was updated to 11.0rc1 from whatever state it was in from prior update a week or three before. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

That gives and maintains 132x43. I don't understand why any font needs to get "loaded" when in a video chip native/proprietary mode is used. Because in 0x30A only about 3/4 of the screen height is used, I tried changing the 08 to 14. That gives 24 rows instead of 08's 43 or 16's 21, and still only uses a short screen.

The standard vga=extended mode has the same behavior. Back in the 2.2.x kernel, I your distribution was most probably just not loading an 8x16 font by default. Now, about your 3/4 of the screen, that most probably is really a problem in the kernel and your proprietary mode, so let's get back to the kernel bugzilla. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
