I'm having two problems with Mint 15, 64-bit Cinnamon edition, updated to current.
First, MDM starts OK, it displays the mouse cursor (it even turns into an I-beam in the correct places), but I can't enter my user name (or even select it). Pressing the Enter key does nothing. Going to a command line, killing mdm by PID, and restarting it doesn't help.
Details: I'm using the proprietary NVIDIA driver (from the repositories), version 304. MDM's at version 1.2.5. I put "vga=791" into GRUB's "GRUB_CMDLINE_LINUX_DEFAULT=" line so that I get a proper Mint plymouth logo (yeah, I know using "vga=" is deprecated, but it still works).
I installed and configured lightdm in MDM's place, and it looks great and all (see [url=http://www.webupd8.org/2012/06/how-to-use-lightdm-instead-of-mdm-in.html]here[/url] and [url=http://forums.linuxmint.com/viewtopic.php?f=211&t=103684]here[/url] for exhaustive instructions), but it installed a bunch of software (parts of Unity) that I don't need. I'd like to go back to MDM.
Second, the majority of the time (probably 80%) I start Chromium, it ends up in a little window in the corner, as in the attached screenshot. Cinnamon thinks it's maximized. Closing it and restarting it (or just starting a new instance) usually gives me a full-screen window.
Any help would be greatly appreciated. Otherwise, Cinnamon rocks.

Re: 2 glitchs: Rendering Chromium, and MDM doesn't work
The problem with MDM is due to my old NVIDIA GeForce 7300 GS card (using the proprietary driver), which doesn't seem to handle the tradeoff from a framebuffer to X very well.
If I take out the "vga=791" line, I get "Linux Mint 15" displayed in an ugly VGA console font, but MDM in HTML mode works fine. If I put in the "vga=791" part, I get a nice-looking Mint logo, but MDM in HTML mode doesn't work. (I haven't experimented with using MDM in GTK mode.)
The preferred solution would be to upgrade to a more modern video card...
As far as Chromium goes, it would appear that the last upgrade to v28.0.1500.52 solved the rendering glitch, at least so far.

Re: 2 glitchs: Rendering Chromium, and MDM doesn't work
Here's a "lightbulb" moment. Ever since Ubuntu Maverick, I've been using the following to fix nvidia-related problems with plymouth, and it finally occurred to me that Mint is an Ubuntu-based distro:
- Install the "v86d" and "hwinfo" packages
- Use the "hwinfo --framebuffer" command from a virtual console (in other words, outside of X) to identify the framebuffer modes supported by my hardware, in order to pick the one I wish to use at boot -- in my case, I like "1024x768-24"
- Change the "GRUB_CMDLINE_LINUX_DEFAULT=" line in /etc/default/grub to read:
- Run "update-grub" as root (or "sudo update-grub")
...and reboot. Plymouth works and so does MDM in html mode.
