1) Upgrade from ubuntu 8.04 -> ubuntu 10.04 can break apt-get
The package flashplugin-nonfree has been problematic when upgrading 8.04 -> 10.04 and breaks apt-get.Bug reported here https://bugs.launchpad.net/ubuntu/+source/flashplugin-nonfree/+bug/429841
Workaround
Open the terminal and run the following commands
sudo rm /var/lib/dpkg/info/flashplugin-nonfree.prerm
sudo dpkg --remove --force-remove-reinstreq flashplugin-nonfree
sudo dpkg --purge --force-remove-reinstreq flashplugin-nonfree
2) Nautilus location bar, bread crumbs vs text based
Breadcrumbs is now the default. The button to switch between the two has been removed. Users can switch with ctrl+l and then esc to revert to breadcrumbs. To permanently switch to text users have to use gconf-editor from a terminal. Note: gconf-editor has been removed from the menus. The key is.
apps>nautilus> preferences> always_use_location_entry
3) Minimize, Maximize and Close button placement
A decision has been taken to move the placement to the left. Mark Shuttleworth explained that this was because "something" is going to be placed in the right hand area in the next release. Moving the buttons now would help enable this change.
The buttons are in the old location on all default themes apart from Ambiance,Radiance and Dust, If you still want the Ambiance ,Radiance or Dust theme but with buttons on the right, choose one of those other themes and use the Customize button to achieve what you want. e.g.
1. System > Preferences > Appearance
2. Select the theme icon "New Wave"
3. Click the button "Customize.."
4. Select tab "Controls" and select "Ambiance"
5. Select tab "Window border" and select "Ambiance"
6. Select tab "Icons" and scroll down and select "Ubuntu-mono-dark"
7. Select "Save Theme" to your choice.
Using gconf-editor is not the right approach as this could bork future themes. This change makes it easier for themes to do interesting things with window borders. Unfortunately, if the wrong approach spreads, they won't be able to do that.
4) Boot options hidden by default on Desktop and Netbook LIVECDs
Workaround
The Ubuntu 10.04 LTS Desktop and Netbook CDs feature a new boot interface that is non interactive by default.
To configure advanced boot options, press any key at the first boot screen.
5) Various users who have ALPS touchpads have reported that scrolling no longer works in the final release
Workaround
Open the terminal and run the following commands
sudo modprobe -r psmouse
sudo modprobe psmouse proto=imps
You should be able to make it permanent by putting:
options psmouse proto=imps
in /etc/modprobe.d/options and rebooting
6) How to Fix the Big and Ugly Plymouth Logo in Ubuntu 10.04
Problem
The logo looks fine when you install Ubuntu, but, after you install the proprietary Nvidia and ATI video drivers, the logo gets bigger and ugly! Below, we provide two fixes for this issue: the first one will fix the resolution of the Ubuntu logo, pretty much like it was when you installed Ubuntu; and the second one will remove the logo, showing only a dark screen until the login manager appears.

Just Installed ubuntu 10.04 on my desktop (fresh installation) – problems with CCSM 3D effects icon not visible and experiencing problems with my GT2200 card.
‘Dos emulator’ does not work.
Onboard network card ( mainboard asus P5KPL-SE) does not always work, have to completely switch off MAINS POWER and restart to clear this issue
Any hints please? or should I revert to ubuntu 9.10?
Thanks
For the Plymouth Logo fix,
in Step 5 (sudo update-grub2)
I was getting “splash: not found”
Solution:
in
gksu gedit /etc/default/grub
at line number 9, instead of
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash nomodeset video=uvesafb:mode_option=1280×1024-24,mtrr=3,scroll=ywrap”
paste this:
GRUB_CMDLINE_LINUX_DEFAULT=”quiet splash nomodeset video=uvesafb:mode_option=1280×1024-24,mtrr=3,scroll=ywrap”
The difference are the double quotes, the correct are the straight ones.
Sorry, the site is not showing the correct double quotes. Correct them in your grub file.
hello. im a new ubuntu 10.04 user and ive recently encountered a problem with it. when i open programs and then type in them, such as “gedit” they automatically close on me. i also cannot start terminal. it will show a loading cursor but no programs appears. i have customized my desktop with compiz. and some themes, as well as using awn. if there is anyone who can help me out there, i would really appreciate it if they could help me out. thankyou. 🙂
I have installed Ubuntu 10 on a Dell system and the top menu bar and bottom panel are not visible. The pointer stops at the top edge of the screen, but no menu. Ctrl-F1 gets me the drop-down menus, origination from the top edge of the screen and I can navigate from there, but cannot get back the menu bar. I’ve reinstalled and installed on another identical system with same results. Ub9 is fine. Kbuntu 10 is also fine. Any ideas? The Optiplex uses on-board Intel graphics chip set.
I should also note that right after install, everything works and looks fine as long as I don’t turn the system off. But after the first reboot the menu bar and panel disappear and leave a blank wallpaper/desktop.
Thanks in advance
