Installation issues

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. At least that's what I thought at the time but it's probably wrong, 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

• Set root partition to (hd0,1) for Windows in GRUB menu. See also here.

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

NOTE!

My windows partition is a FAT32. This is because, after restoring it, AND BEFORE ever starting it, I renamed the file <windows-dir>/system32/convert.exe. I found this info somewhere on the net, see for example here: after install/restore, Windows filesystem is actually FAT32, and it's converted to NTFS only at the first run. This is useful as FAT is better supported by Linux.

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).

• I enabled Fn + F5 creating file /etc/modprobe.d/ibm_acpi.modprobe with the following line:

options ibm_acpi hotkey=enable,0xff9f

• Modified my GRUB menu.lst. The Fn + F5 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 here. All this should revert to normal without passing options to ipw2100.

• 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.

Dapper upgrade

TODO

All fine.

Configuration files

• xorg.conf
• interfaces
• GRUB's menu.lst
• Windoze boot.ini

Current issues

• How can I switch Fn and Ctrl keys? (I guess I can't as Fn combinations are interpreted by the BIOS)

• Enable scrolling and keep functionality of mouse 2 button. For the moment I'm using button 2 to scroll, and emulating 2=1+3 to paste. See the "InputDevice" section in my xorg.conf

• FnF7 does not work

Still untested

• Irda
• modem
• IEEE 1394
• Parallel port
