Setting this to confirmed as it has been independently verified.
** Summary changed:
- [gutsy] regression: suspend fails to resume (no restricted drivers installed)
+ [hardy] regression: suspend fails to resume (with or without restricted
drivers installed)
** Description changed:
- Binary package hint: linux-source-2.6.22
+ I have been using Ubuntu since Hoary Hedgehog on a Dell Preicision M70
+ laptop (NVidia Quadro FX Go1400). Suspend-to-ram began working fine
+ starting with the Edgy Eft. It worked fine on Feisty as well. Starting
+ with gutsy, suspend-to-ram fails to work on the default installation.
- On a Dell Precision M70 laptop (NVIDIA QuadroFX Go 1400), suspend/resume
- has always worked fine with restricted installed in both edgy and
- feisty. With fully updated gutsy, laptop suspends but does not resume. I
- have tried all the following combinations:
+ Tested with: hardy alpha 6
+
+ Symptoms: laptop suspends but does not resume. I have tried all the
+ following combinations:
- No restricted drivers
- Restricted driver + compiz
- Restricted driver + metacity
- In the first case, nothing comes on the screen after attempting to
- suspend---just a hard lockup. In the latter two cases, I see some text
- messages printed to screen and a few screen resolution changes before
- hard lockup.
+ In all cases, nothing comes on the screen after attempting to suspend---
+ just a hard lockup.
- EDIT: (Oct 13 2007)
+ In the latter two cases, the problem can be fixed simply by setting
+ POST_VIDEO=false in /etc/default/acpi-support.
- WORKAROUND: with restricted drivers and -14 kernel installed, set
- POST_VIDEO=false in /etc/default/acpi-support. Suspend will work. Thanks
- to gerard76.
-
- Without restricted drivers, suspend still fails.
+ The main purpose for this bug report is to alert whoever is responsible
+ for ACPI that this minor change in acpi-support will fix this very
+ frustrating regression, as long as restricted drivers are installed.
