My fix being reinstalling unity-greeter. It installs a whole lot of stuff, one of which surely fixed my low resolution issue. For some reason I can't list the other greeters in lightdm.conf as doing so gives a low resolution message. So I'm stuck with unity-greeter, but at least I can run lightdm rather than gdm, which is flaky.

Machine: i5-2500K + Z68 chipset Monitor: 42" TV, HDMI The problem did not exist when using 12.04. When upgraded to 12.10, sometimes (> 70%) during boot up it says "the system is running in low graphics mode" and the login screen won't even show up. The problem for 12.04 is that the screen resolution can only go up to 1366x768, but 12.10 can go with 1400x900 (however my TV actually support 1920x1080p. I installed everything from the default ubuntu repositories, no thirdparty graphics drivers installed. And I guess the Intel graphics driver is already in the mainline kernel? one more thing, if I goes to command line, and type "sudo service lightdm restart", I can still enter the desktop, so the problem seems not like a persistent one, more like some kind of timing issue (that's probably why it is not happening every time).
