Package: lightdm
Version: 1.10.3-3
Severity: normal
Dear Maintainer,
After I had switched from X to VT several times (maybe there are other
cuases too, but I don't know them) X stopped updating windows. The mouse
cursor was moving and changing its shape as I moved it over different
windows. I could still switch betwen VT and X. On VT I found that,
apparently, lightdm wan't handling data from X properly because there
was over 200kB worth of data waiting in X's send queue and 8k in receive
queue in lightdm.

The numbers had been growing each time I switched between X and VT.
I had reported[1] this problem to the lighdm mailing list but there was no
response.
