Dunno if I'm using XGL. How do I tell? It doesn't appear anywhere in my
xorg.conf, and the package xserver-xgl is not installed, so I guess I'm
not using it.

Mine is slower too.
Just set it back to normal look.
I have an intel 855

One of places that I noticed is the bottom bar. I have speed applet 
(netspeed_applet2 0.14) and it doesn't update.

Please keep the old IDE chipset drivers so that external CD writers can work

2008-04-02 Thread Wenzhuo Zhang 

Hi,

Starting from Gutsy, the old IDE chipset drivers are no longer included in the 
kernel package. The libata based drivers, being cleaner and easier to maintain, 
have taken the places of the old drivers.

However, external CD writers don't work with the new libata based IDE drivers. 
Please see bug report #109211 
 for 
details. Considering that external CD/DVD writers are widely used hardware, I 
suggest keep the old IDE drivers until this bug is fixed, so that users can 
still use their external CD/DVD writers in Ubuntu after very little manual 
configuration. They should not conflict with anything if not loaded.

I'm gonna stick with it for a while and see if it improves or I can fix
it.

The latest updates I downloaded today seem to have improved it a bit.
It's definitely faster now than before. But it's still noticeably slower
than compiz or metacity with no compositing.

Could this be my problem? See post "Help with Gutsy upgrade" in this 
list. After an upgrade from Feisty to Gutsy the new kernel will not load 
my hard drive. When I upgraded from Dapper to Feisty, the upgrade set my 
drives up as /dev/sdx (in GRUB and /etc/fstab) and I could not boot. I 
changed the drives back to /dev/hdx and that solved the problem. Gutsy 
does not seem able to deal with /dev/hdx so, could this be why I can't 
boot the 2.6.22.14-generic kernel? I have a 4 year old Soyo motherboard 
with Via chipset. Can I rebuild the kernel to get this older IDE 
support? I can still boot into my Feisty kernel.

Nowadays the standard way of identifying filesystems is by UUIDs. You should
use the vol_id command to find out the UUIDs of your filesystems, e.g.

$ sudo vol_id /dev/hda1

and replace the occurrences of "/dev/[sh]dx?" in /etc/fstab and 
/boot/grub/menu.lst to "UUID=", where "" is the corresponding 
UUID of each filesystem.

If you have added the old IDE driver modules to /etc/initramfs-tools/modules
before, you should remove them fist, and run the following command for each 
kernel
version:

$ sudo update-initramfs -u -k 

If you have not modifiled /etc/initramfs-tools/modules before, probably your 
IDE chipset is not supported by libata yet. You may want to file a separate bug 
report at launchpad, attaching the result of "lspci -vvn", "dmesg" of a running 
kernel, and a screenshot (by a camera) of the boot failure of Gutsy.

If your chipset is not supported by libata, and you want rebuild the kernel
to add the old drivers back, following the instructions on this web page:
