| − | 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.
| + | |

| − | 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.
| + | |
| − | | + | |
| − | 6. Can't find KNOPPIX filesystem. sorry.
| + | |
| − | | + | |
| − | Hardware:
| + | |
| − | *Sony Vaio N505SN laptop
| + | |
| − | *PCMCIA CD drive
| + | |
| − | | + | |
| − | Boots fine, starts searching for hardware:
| + | |
| − | *Scanning for USB/Firewire devices...Done
| + | |
| − | *Enabling DMA acceleration for: hda
| + | |
| − | | + | |
| − | Then fails with "Can't find KNOPPIX filesystem. sorry.", and drops into a mini-shell
| + | |
