It keeps saying this and won't let me post, despite my post not having anything which looks like a link in it.

(My question was actually this:

I'm imagining that I can somehow configure the screensaver so instead of kscreensaverrc saying

Saver=lattice.desktop

it says something like

Saver=optirun lattice.desktop

but just doing that didn't work. Can it be done? Maybe I'm just missing some detail.)

[Buddlespit]

Looks like you made it in

[FatUglyGeek]

Now perhaps I can ask a question:

I'd like to have my Really Slick Screeensaver run using Optirun - glxspheres gets me about 50 but vblank_mode=0 primusrun glxspheres is more like 250. I've been searching but have been unable to find the answer/ask the right question. I have found kscreensaverrc which holds the name of the screensaver and the time limit, etc. Can anyone help? I'm imagining that I can somehow configure the screensaver so instead of kscreensaverrc saying

Saver=lattice.desktop

it says something like

Saver=optirun lattice.desktop

but just doing that didn't work. Can it be done? Maybe I'm just missing some detail.

Hopefully my question makes sense. Thanks in advance.

Got there in the end. What is it about that post which upset the system? Oh well, if anyone can help with my screensaver question I'd be most grateful.

Try

texture_tiling=false s3tc_enable=true vblank_mode=0 optirun -b primus <application>

. That's what I use after testing to get maximum performance and least issues. You are still using primus backend though.

I tried that. After the appropriate period it just goes straight to a "the session has been locked" page instead of showing the screen saver.

System Settings-->Display-->Screen Locker?

[FatUglyGeek]

Yes. That doesn't seem to be using my extra video hardware though (it's an Alienware Mx11R3 with the dual video setup). The Screen Locker page just lets me choose from a list with no access to anything more than what I'd see on the settings page if it was Windows. I was hoping for a more direct approach which might let me tell it to run the screensaver using optirun. In Windows I'd dig around in the registry but Kubuntu is different.

Odd question, but why would you ever want to run your screensaver on your discrete card? It just uses more power, creates more heat and is absolutely unnecessary. Anyways hit me up with the following results:

optirun --status
glxinfo | grep OpenGL
optirun glxinfo | grep OpenGL
primusrun glxinfo | grep OpenGL
cat /etc/bumblebee/bumblebee.conf
cat /etc/bumblebee/xorg.conf.nvidia

I'm not an admin but my guess is they have the site's software set to somewhat paranoid, it's to keep spammers and bot-spam out, we've all been there, you're good now.

[FatUglyGeek]

If I used the screensaver concept purely functionally then I'd just have it turn the screen off. I want it to look pretty. I'd like to run the Hyperspace screensaver but my default GPU can't handle it, I'm sure the Nvidia one will. It won't be the end of the world if I can't get it to work but you don't get anywhere by not trying, do you? Thank you for trying to help though.
