Machine: ASPIRE 5741 OS: Ubuntu 12.04 (kernel updated to 3.2.0-29-generic) Symptom: screen remains black after resume from suspend, power LED is on, HDD light continuously blinking
Hi guys, I had the above problem and have been looking for the solution. Last night, I realise that it actually my machine displays login screen (and I can login) but LED back light is off so I couldn't see it. This issue is very similar to what I had during the Ubuntu 12.04 installation, thus I tried a solution in the same line. SOLUTION WORKED FOR MY CASE: 1. open grub file by: sudo vim /etc/default/grub 2. modify the corresponding lines as: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi_backlight=vendor" GRUB_CMDLINE_LINUX="acpi_osi=Linux" 3. reboot grub by: sudo update-grub. I hope this helps some of you. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/999638 Title: Acer Aspire One 722 doesn't resume from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pm-utils/+bug/999638/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
