So it is me with Dell Inspiron 5100 again. To answer Lethe's question, the model is identified as:
sudo dmidecode | grep 5100 Product Name: Inspiron 5100 I attached the output of dmidecode on my laptop previously, I understand that most info should be there. Please let me know if you need more information beyond that. I recompiled the kernel with the only change being that in /drivers/input/keyboard/atkbd.c, the line DMI_MATCH(DMI_SYS_VENDOR, "Dell Inc."), replaced with DMI_MATCH(DMI_SYS_VENDOR, "Dell Computer Corporation"), and now the recompiled kernel indeed does not have any problem with Fn+Up, Fn+Down keys on my machine. Of course, this kernel would not work for those Dell laptops which are from "Dell Inc.". So it is really about differences in how these laptops identify themselves. -- Losing keyboard and mouse control when changing screen brightness with fn + arrow under intrepid https://bugs.launchpad.net/bugs/285323 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-power-manager in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
