Hi everybody,
LFS/BLFS system.
i686-pc-linux-gnu 2.6.19.2
CUPS 1.2.7. Parallel printer (garden variety).
Udev 056 (LFS circa Sept. 2005)
Works perfectly.
BTW, by "perfect" here I mean the basic functions work clean and fully:
- Graphics (Xfree86-4.6)
- Networking
- Sound
- Printing
(other functions are nice to have but not relevant here).
Created a replica of the above system on a different drive.
Obviously, worked identically, but then
I installed the latest (104) Udev
(same functionality as 103 except for some "bug fixes") from sources. No other
changes/additions/removals.
To my amazement, I've somehow managed to put together a "clean" new Udev system
in spite of the atrocious documentation (especially the lack of coverage of the
concept change - elimination of the 'hotplug', etc.) and support.
That is, everything works fine and identically as hoped EXCEPT Printing which
has been lost completely.
A few details of the PROBLEM:
1. No printing whatsoever (No 'lp/lpr <file>', etc.).
2. 'cat <file> /dev/lp0' works OK!.
3. On any attempt to print (other than 'cat' above) the "external" symptom
looks like the <file> never "physically" reaches the printer.
4. The "internals" ('error.log', 'access.log', etc.) do not show any kind of
errors, even with 'cups.conf' on "debug2" (it's as if the file never leaves the
"queue" - 'lpstat' shows the file sitting there forever; however, the printer
_is_ "accepting").
5. In /dev, "crw-rw---- 1 lp lp 6, 0 lp0" (identical with the original system).
6. Variations thereof: more permissions, change owner, group) - no cigar.
7. A strange difference between the original (056) and the new (104) system:
in '/dev' there's no longer a '.udevdb' directory. Instead, there's a new
'.udev' with a 'db' subdirectory containing some wacky symlinks pointing to
non-existent targets (but close).
There's a good chance the clue is here but I can't fathom it.
8. Same behavior whether I switch to 2.6.19.1 and/or build 'lp' as a module or
in the kernel.
Any ideas?
Thanks in advance,
