The Usual Nvidia Complaint

[Snowhog]

Alt+F12 I think. Not at my PC, so can't verify.

[JillSwift]

Close, shift-alt-F12

No I need the

Command to type into the Terminal

At the Boot screen That says Try or Install. I can press Ctrl+alt+F2 and access the Terminal.

Let it go to a desktop (the Try option), then hit alt-shift-f12 to disable effects. From there you can proceed with the install

The key combo might work at the try/install prompt.

It never makes it to the desktop, when it goes to the desktop, I get this pretty blue screen with diagnal lines, and Ctrl+Alt+F12 does not do anything.

Can you answer my question on the Command?

Do you know what the command is to turn off Effects? I did a search, but what I came up with did not work.

[JillSwift]

Try from a console:

kwriteconfig --file kwinrc --group Compositing --key Enabled false

If that doesn't work (and I don't know if KDE needs to be running for it to work) you might be able to get the same effect by adding the lines

[Compositing]
Enabled=false

Or change Enabled if it's already there, etc.

to the file

~/.kde/share/config/kwinrc

Restart the whole shebang with

sudo service lightdm restart

Or reboot as is your preference.

I did, but you didn't listen
alt-shift-f12

Just tested this, at the beginning where you choose to try or install, this key combo disables desktop effects.

Ii don't know if it will work from a vt (the full-screen ctrl-alt-fxx command prompt) as I don't off the top of my head know how to specify which "screen" has kwin running in the command, but there is this if you can open a konsole window:

qdbus org.kde.kwin /KWin org.kde.KWin.toggleCompositing

[claydoh]

Try:

kwriteconfig --file kwinrc --group Compositing --key Enabled false

If that doesn't work (and I don't know if KDE needs to be running for it to work) you might be able to get the same effect by adding the lines

[Compositing]
Enabled=false

Or change Enabled if it's already there, etc.

to the file

~/.kde/share/config/kwinrc

Restart the whole shebang with

sudo service lightdm restart

Or reboot as is your preference.

This will work, but you would have to stop kwin first, then reload it - hence the need for a konsole window
kquitapp plasma-desktop
kwin --replace

Also note that unless the live session has persistence enabled when it was created, these config settings likely won't stick on a reboot of the installer, or restart of lightdm

[JillSwift]

Dangit, I forgot this was in the context of the liveCD/USB installer.

[claydoh]

It *might* stick through a restart of lightdm, though.

[JillSwift]

Just tested manually editing on my laptop, and:

• "Enabled" isn't in the very basic config, you have to add it manually.
• It sticks through a lightdm restart
• You may want to also change "OpenGLIsUnsafe" to true

To get back to the GUI, that's on console 7 (ctrl-alt-F7)

I'm curious, what GPU do you have anyway? Alt+Shift+F12 got the live session working for me

[jpenguin]

I guess you could always do a CLI-Based server install, then a 'sudo apt-get install kubuntu-desktop'

[Robtygart]

I will keep on working on it. Thanks for all the suggestions....

Claydoh alt-shift-f12 worked for me after such a long time trying and searching web. I was trying to install 14.04 on pc with geforce 6600 GT graphics card and everytime the cd booted to the desktop I had garbled graphics and no panel. I could click on the install icon but only reached as far as disk partitioning and then the install stalled with graphics pixelated. Tried your suggestion an instantly worked. Thanks but its a pity that in 2014 that a known issue is not fixed, no mention of it, as far as I could see on kubuntu web site. This is a potential put off for anyone trying kubuntu. Now I hope I can install nvidia driver after install.
