Dan's questions

I have an Nvidia GeForce GT 635, and I installed the drivers for it with ubuntu-drivers autoinstall, but now my screen resolution is off and can't be changed in the display subsection of the system settings. Specifically, my screen resolution is stuck at 1024x768 (with no other options presented) while my native resolution is 1920x1080.

Relevant lspci lines:

01:00.0 VGA compatible controller: NVIDIA Corporation GK208 [GeForce GT 635] (rev a1)
Subsystem: NVIDIA Corporation GK208 [GeForce GT 635]
Kernel modules: nvidiafb, nouveau, nvidia_367, nvidia_367_drm
01:00.1 Audio device: NVIDIA Corporation GK208 HDMI/DP Audio Controller (rev a1)

How can I change my display back to its native resolution?

I installed the package cantor-backend-sage, and then started up cantor, but Sage isn't one of the options for the backend when it starts up. How can I get cantor to use sage as a backend?

I have a hard drive in my laptop with a windows and an ubuntu partition. I got an SSD to replace my hard drive, but it has a slightly lower capacity. I've already partitioned the SSD to the sizes I want, and each partition on the new disk is larger than the amount of used space on my old hard drive.

I was going to use dd, but it appears that it requires partitions to be the same size.

How can I copy my old partitions onto my new ssd? I'm copying my boot partition too, so how can I make sure the new disk is bootable, and the new partitions are exactly the same as the old ones (but with less free space)?

I have both Greatest Hits by the Offspring and Greatest Hits by Queen in my Rhythmbox library. When I sort by album, it looks like this:

How can I tell get rhythmbox to sort by album in such a way that it doesn't interleave albums by different artists with the same name?

I use Zotero to organize papers and sync between my home and work computers. I've got enough papers that Zotero's 100MB free limit is looming.

Is there a way to retarget Zotero to use Ubuntu One's cloud storage instead of Zotero's?

I need to present a slideshow on a projector. I know that if I use openoffice it can send a seperate image to the laptop screen and the projector.

If I have some other application (like a PDF viewer) being used to view the slideshow, how can I make the presentation display on both the screen and the projector?

What can replace system monitoring in the top Gnome Panel in Unity?

I'm using gnome 2 right now and looking to switch to unity, but one thing that I really miss is the old gnome 2 system monitor:

I found something like this for KDE, but the bars were really thin and didn't give a good idea of the recent history of some system's usage.

Is there something like this that I can embed in one of the taskbars in Unity?

Failing that, is there something like this for any desktop environment other than Gnome 2?

When I try to run the game Cogs from the command line, the game spits out the following error and dies immediately:

Couldn't set 800x600 OpenGL video mode: Couldn't find matching GLX visual

What does this mean, and how can I fix this?

Edit: I have an intel graphics card.
