Hi I have a Medion MD5400 laptop (https://wiki.ubuntu.com/LaptopTestingTeam/MedionMD5400). I have upgraded Breezy to Dapper (kernel 2.6.15-23) but it seem to have broken suspend to RAM although hibernate does work. Suspend to RAM also works in Hoary. My first impression was that it was a kernel issue.
Issuing suspend with "sudo /etc/acpi/sleep.sh" result in the following error message: "ERROR: Couldn't attach to DCOP server!" Issuing suspend from Power Manager or the logout menu result in successful suspending with a blinking led. On resume the screen comes back correctly to the lock screen. However, the keyboard is unresponsive (caps-lock does nothing!) so I can't type anything. Hard poweroff is the only way out. On a positive note, booting with grub options "init=/bin/bash vga=0" and issuing "echo -n mem > /sys/power/state" does suspend and resume correctly (keyboard responds). Is this then a user-space issue? Could this be due to upgrading rather than doing a clean install? Thanks, Kashif lspci: 0000:00:00.0 Host bridge: Silicon Integrated Systems [SiS] SiS645DX Host & Memory & AGP Controller 0000:00:01.0 PCI bridge: Silicon Integrated Systems [SiS] Virtual PCI-to-PCI bridge (AGP) 0000:00:02.0 ISA bridge: Silicon Integrated Systems [SiS] SiS962 [MuTIOL Media IO] (rev 04) 0000:00:02.1 SMBus: Silicon Integrated Systems [SiS] SiS961/2 SMBus Controller 0000:00:02.5 IDE interface: Silicon Integrated Systems [SiS] 5513 [IDE] 0000:00:02.7 Multimedia audio controller: Silicon Integrated Systems [SiS] Sound Controller (rev a0) 0000:00:03.0 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f) 0000:00:03.1 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f) 0000:00:03.2 USB Controller: Silicon Integrated Systems [SiS] USB 1.0 Controller (rev 0f) 0000:00:06.0 Communication controller: Intel Corporation 536EP Data Fax Modem 0000:00:08.0 Ethernet controller: Realtek Semiconductor Co., Ltd.
