Hi, I also have what I take to be this problem. I have a very different system to those above, I have a Dell Studio XPS (L501X). Suspend/resume worked fine on 10.10. On 11.04 suspend works fine; on resume the hard drive lighjt flashes, the computer seems to wake up, the screen powers on, but then everything locks. I cannot get a virtual terminal, and have to hold the pwoer button for 4 seconds to power off; nothing else works.
I have not tried apport yet (I can do if you want, although since this page is getting full I'll wait until it's requested). However, I did follow the advice on https://wiki.ubuntu.com/DebuggingKernelSuspend and used the system RTC to gain some information. The relevant dmesg entries appear to be: [ 1.549795] Magic number: 0:846:372 [ 1.549797] hash matches /build/buildd/linux-2.6.38/drivers/base/power/main.c:535 [ 1.549831] pci 0000:ff:00.0: hash matches [ 1.549834] pci 0000:02:00.0: hash matches Where lspci gives me: ff:00.0 Host bridge: Intel Corporation Core Processor QuickPath Architecture Generic Non-core Registers (rev 05) and 00:02.0 VGA compatible controller: Intel Corporation Core Processor Integrated Graphics Controller (rev 18) among other things. I am guessing this means the problem is in the control of the Intel graphics card? But I am not an expert (or anywhere near) in these matters. As I say, there were no problems in Ubuntu 10.10.....! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/787203 Title: ubuntu 11.04 will not wake up from suspend To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/787203/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
