Currently running: Kubuntu 7.10 (Gutsy).
I first installed Kubuntu 5.10 (Breezy). I wanted to keep Windoze, just in case I needed it (but I never use it ;) ), and keep the hidden protected area, and be able to reach it at startup, just in case I sell the laptop back at some point. My problem was that:
- GRUB has to be installed either in the MBR or in the first partition. As an alternative I could have used the NT boot loader, see here. Anyway, I wanted to keep Linux in front, as I plan to remove windoze completely, and the first part of the disk should be faster.
- Windows would only work being on the first partition (AFAIK)
- Putting GRUB in the MBR would overwrite the original setup/recovery tools (AFAIK - Note: if you do this, and later manage to start Windows, it will rewrite the MBR anyway)
My solution (DO IT AT YOUR OWN RISK):
- Create a new primary partition for Windows, at the end of the disk, before the rescue partition. Copy windows there.
- Modify windows' boot.ini:
$ diff /windows/boot.ini /windows/boot.ini~
3c3 < default=multi(0)disk(0)rdisk(0)partition(2)\WINDOWS --- > default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS 5c5 < multi(0)disk(0)rdisk(0)partition(2)\WINDOWS="Microsoft Windows XP Professional" /fastdetect --- > multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Microsoft Windows XP Professional" /fastdetect
My current partition table according to fdisk:
Disk /dev/hda: 36.8 GB, 36825459200 bytes 255 heads, 63 sectors/track, 4477 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/hda1 * 1 6 48163+ 83 Linux /dev/hda2 3651 4477 6642877+ b W95 FAT32 /dev/hda3 7 249 1951897+ 82 Linux swap / Solaris /dev/hda4 250 3650 27318532+ 5 Extended /dev/hda5 250 3650 27318501 83 Linux Partition table entries are not in disk order
Breezy Post-install configuration
- (I think I) modified interfaces to enable hotplugging the ethernet cable. Which is wrong anyway. I also had to add lines to dhcp on both the wireless (eth0, see below) and the ethernet (eth1). Dapper upgrade removed hotplug, and it's still working, so that was really useless.
- I enabled + creating file /etc/modprobe.d/ibm_acpi.modprobe with the following line:
options ibm_acpi hotkey=enable,0xff9f
- Modified my GRUB menu.lst. The here. After Dapper upgrade I further cleaned up the script. Now the wireless is disabled at boot, which is what I wanted, and is switched with + . + stopped working.. Finally I found out why looking at /usr/src/linux-source-2.6.12/Documentation/networking/README.ipw2100 in section rf_kill, and modified /etc/acpi/wireless.sh accordingly, see
- I thought the built in wireless did not work, but in fact it does
- I had an hissing sound when on batteries. I found out it's actually related to screen brightness, see here.
All went fine.
- This bug does not seem to present itself, and CPU scaling is still working fine.
- With xorg version 7.0 I managed to enable scrolling and keep functionality of mouse 2 button. See also How to configure the TrackPoint.
- Hybernation is now working. With Breezy, the system used to crash and reboot after resume.
- With ibm-acpi ver. 0.8-2 I can now use the experimental settings, adding option experimental=1 to /etc/modprobe.d/ibm_acpi.modprobe.
Attempted Edgy upgrade
This was a disaster. apt-get got completely confused, grub messed up and at boot it could not find any of the kernel images on disk. As I was far back on the ubuntu release schedule anyway, I opted for plan B: fresh install of Gutsy.
This went perfectly. I kept home partition and formatted the rest, which allowed me to keep most of the settings I had. Now I'm in the process of restoring previous tweaks.
- Sound did not work at first: I just had to turn on and pull up the PCM output in kmix.
- Fonts look uglier, dirty and fat.
- tty1-6 disappeared, clicking here. In my case I had to unban and load radeonfb, and add vga=792 to the boot options. Now I have the ttys but the boot splash does not work, so I removed the splash boot option. just showed a blank screen. Found a solution
- Installed kmilo-legacy to recuperate the OSD and special button functions, replaced 0xffff8f with 0xffffff in /etc/modprobe.d/thinkpad_acpi.modprobe to enable to
options thinkpad_acpi hotkey=enable,0xffffff experimental=1
This time the wireless switch works out of the box, but if I press volume keys kmilo decides that I also want to start kmix and change its master volume as well, together with /proc/acpi/ibm/volume. I found I can suppress this by pressing.
- For most other things I definitely noticed an improvement in stability, usability, etc.
Configuration files (Dapper)
Configuration files (Gutsy)
- How can I switch and keys? (I guess I can't as combinations are interpreted by the BIOS)
- does not always work
- I'd like to use an ACPI key combination to restart X, as sometimes everything freezes, keybord included, but key combinations as brightness, thinklight, still work.
- modem (recognized by restricted driver module in Gutsy)
- IEEE 1394
- Parallel port
