I managed to work around the lost wacom pen after resume. For me the /etc/acpi/resume.d/20-setserial.sh with "setserial /dev/ttyS0 port 0x0200 irq 5 autoconfig" is not enough. In addition the serial port needs to be initialized in boot. I noticed that I can rescue the serial by stopping X and doing the setserial it in text mode. After that the wacom pen is functional also after suspend/resume. So I dpkg- reconfigured setserial to manual and created /etc/serial.conf with "/dev/ttyS0 port 0x0200 irq 5 autoconfig". So apparently the serial port needs some of the magic done by setserial before xorg opens the device.
But during testing this I noticed a more disturbing issue. Sometimes resume from RAM reboots! Eek. Is there an existing bug for this kind of behavior? -- Serial port stops working after suspend https://bugs.launchpad.net/bugs/105380 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
