List V3.8.1 bugs here

1. No USB keyboard support on Dell Optiplex GX280. (SOLVED)

Some hardware details:

* USB Keyboard: Happens to be a Danish keyboard, shouldn't matter.
  * SUSE identifies the keyboard as "Dell USB Keyboard Hub" and uses the hid driver
* USB Mouse
* Pentium 4
* SATA hard drive

symptoms:

* Keyboard works at the "KNOPPIX: " boot prompt, anything after that it doesn't
* above the "Welcome to KNOPPIX... (etc)" white text line, you have:
    1. image of tux
    2. audit(somenumber.???:?)
    3. ata2: disabling port
  it's that 3rd line that perplexes me.
* Hangs 30 seconds into booting, immediately after message: "2.78 Knoppix booting"
* It seems it never detects anything USB (though the USB mouse kinda works later...)
* booting "debug" asks to type exit to continue... nothing responds on the keyboard
* booting "failsafe" makes it all the way to KDE where the mouse (mostly) works, but the keyboard does not.
* booting "expert" fails when it needs KB input to select SCSI drivers.
* booting the {nousb|nousb2|lang=da} all fail.
* booting "knoppix testcd" fails similarly
* booting "failsafe testcd" tests the CD and makes it into KDE as prev. mentioned

ideas:

* ?? I've tried a lot of tweaking and some searching, anyone experiencing similar issues?
* Is anyone having success with 3.8.1 and a new Dell?

solution: booted with "knoppix acpi=off" and all was well. Apparently this Dell gx280 uses a 'difficult' power management ... chipset (likely the wrong word.)

suggestion: list acpi=off in the F3 list of boot parameters, it's more pertinent than some of the others that made the list.

--Jvw 16:49, 11 Apr 2005 (GMT) Damn you beat me on the first one ;-)

With knoppix 3.8.1 (english) on an IBM x335 machine and console attached via a console chain cable the keyboard becomes inoperative after Knoppix has booted. After the CPU tuxes the following lines are written to the console:

i8042: Can't read CTR while initiating i8042
ide2: I/O resource 0x1E8-0x1EF not free
ide2: ports already in use, skipping probe

This did not happen with Knoppix 3.4 (english). Just to let you know. For further information please write: jvwCHANGETHISTOATSIGNiwr.fzk.de


3. Typo

If you open K Menu -> KNOPPIX -> Utilities you will see "Chose/Restart KNOPPIX Desktop." That should read "Choose/Restart KNOPPIX Desktop." Just a small typo, but it seems to have escaped the developer's watch in the last few releases.

4. USB2.0 Storage device slow speed

[CLH] USB2.0 external hard disk is auto-mounted as ub device, which is using USB 1 transfer speed, far slower than using sd_mod. for example, trying to mount /dev/sda1 gives error because module sd_mod is not available (modprobe sd_mod gives error) should recompile kernel with scsi module (sd_mod) support. Also check out the usbmount http://usbmount.alioth.debian.org/ which automount external USB storage devices , I tried Ubuntu liveCD and it worked well at USB2 speed.

5. Keyboard not working after loading

Hardware Details:

*Dell Latitude D610

Error Messages:

*i8042: Can't read CTR while initiating i8042
*ide2: I/O resource 0x1E8-0x1EF not free
*ide2: ports already in use, skipping probe

After that point it seems the keyboard is non-functional. Touchpad/eraser are not functional either. Doing a "shutdown" will get to the point of "eject CD and hit return" keyboard still not functional. Worked fine in English V 3.6. USB Mouse works.

have you tried the acpi=off boot parameter? our machines may share a similar (Dell) issue.
