I don't think this is a Unity bug at this time, but I'll leave it in the Triaged state just in case. Adding xserver-xorg-video-intel since this is where I think the problem is.

On login, the desktop icons move back and forth several times, I believe this correlates with ~/.xesssion-errors 'unity main process ended' messages like: upstart: gnome-keyring main process (7364) killed by TERM signal upstart: at-spi2-registryd main process ended, respawning upstart: at-spi2-registryd main process ended, respawning upstart: at-spi2-registryd main process ended, respawning upstart: at-spi2-registryd main process ended, respawning upstart: at-spi2-registryd main process ended, respawning upstart: at-spi2-registryd main process ended, respawning upstart: at-spi2-registryd main process ended, respawning upstart: at-spi2-registryd main process ended, respawning upstart: at-spi2-registryd main process ended, respawning upstart: at-spi2-registryd main process ended, respawning upstart: at-spi2-registryd respawning too fast, stopped upstart: unity7 main process (7477) terminated with status 1 upstart: unity7 main process ended, respawning upstart: unity7 main process (7910) terminated with status 1 upstart: unity7 main process ended, respawning upstart: unity7 main process (7939) terminated with status 1 Then after login unity/compiz is basically unusable. compiz has $ pidof compiz 8144 $ cat /proc/8144/statm 424082 75989 15631 3 0 241850 0 $ cat /proc/8144/status Name: compiz State: S (sleeping) Tgid: 8144 Ngid: 0 Pid: 8144 PPid: 7240 TracerPid: 0 Uid: 1000 1000 1000 1000 Gid: 1000 1000 1000 1000 FDSize: 64 Groups: 4 20 24 46 104 116 118 124 126 127 133 1000 VmPeak: 1764100 kB VmSize: 1694584 kB VmLck: 0 kB VmPin: 0 kB VmHWM: 302272 kB VmRSS: 302092 kB VmData: 965520 kB VmStk: 136 kB VmExe: 12 kB VmLib: 101692 kB VmPTE: 1504 kB VmSwap: 0 kB Threads: 8 SigQ: 0/15005 SigPnd: 0000000000000000 ShdPnd: 0000000000000000 SigBlk: 0000000000000000 SigIgn: 0000000000001000 SigCgt: 0000000180014003 CapInh: 0000000000000000 CapPrm: 0000000000000000 CapEff: 0000000000000000 CapBnd: 0000003fffffffff Seccomp: 0 Cpus_allowed: 3 Cpus_allowed_list: 0-1 Mems_allowed: 00000000,00000001 Mems_allowed_list: 0 voluntary_ctxt_switches: 269139 nonvoluntary_ctxt_switches: 116421 top shows compiz eating anywhere from 40 to 80% cpu, and having 300M resident memory. Additionally, Xorg is sitting 5-20% while I'm typing this in firefox. The only application I have open at the moment is gnome-terminal and firefox. My previous attempt to use chromium left its window un-resizable.
