Sony Vaio VPCZ11 with Kubuntu Oneric

Posted on October 20, 2011, 11:58, by wodka, under Uncategorized.

Everything works except keyboard backlight. But this can be reenabled by calling:

sudo sh -c ‘echo 1 > /sys/devices/platform/sony-laptop/kbd_backlight’

SVN Hooks

Posted on April 12, 2011, 15:37, by wodka, under Uncategorized.

Hi there, within a big php project you make typos. here is a small prehook script for svn that will actually prevent commits with several common and annoying mistakes:

Spaces in filenames
Spaces prior to the first <?php tag
PHP Short Tags
windows line endings

#!/bin/bash

# configuration
DO_DOS_FILE_CHECK=1
DO_SPACE_FILE_CHECK=1
DO_PHP_SHORT_TAG_CHECK=1
DO_SPACE_BEFOR_PHP_CHECK=1

TXN="$2"

Kubuntu 11.04 Upgrade “no init found. try passing init= bootarg”

Posted on April 5, 2011, 17:20, by wodka, under Uncategorized.

Hi there,

yesterday I did a small dist upgrade that actually bricked my system. The only thing I was able to reach was busybox which told me after invoking “sh init”

mount none failed for /dev, device busy
mount none failed for /sys, device busy
…

Booting from a Live CD showed that I was indeed able to mount the partitions without any trouble. Invoking update-grub or update-initramfs did’t improve the situation.

What finally worked was to disable the raid autodetect in grub:
