Title:
Ubuntu 14.04 blank screen after wakeup from sleep
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
This is my re-reporting of bug #1283938, after it was downgraded and
the specifics of the tested fix did not apply to me. We were
encouraged to re-report.
On a fresh installation of Xubuntu 14.04 (64 bit) on my Toshiba
Latitude L755 laptop, when I close the lid, the screen shuts off (as
would be expected). When I open it again, it gives me the chance to
log in as though the screen was locked. After typing my password and
hitting enter or clicking through to continue, the screen blanks and
the computer cannot be awakened. Restarting is necessary.
I have seen others report this using Unity desktop as well. My
personal experience is that LXDE (installed after the fresh Xubuntu
install as an attempt at a work-around) is unaffected by this bug. I
have been affected since my initial 14.04 install in April and updates
have not altered it.
