Hi everyone. This thing took me almost a month to figure out, so I thought it is worth posting the solution here as well. My original thread is on ubuntu forums [SOLVED] Hotkeys on acer with 64 bit os-how to? - Ubuntu Forums](http://ubuntuforums.org/showthread.php?t=1256788). To summarize in few sentences: I bought a brand new laptop Acer Emachines G725 and I couldn’t make my hotkeys for birghtness work (Fn+Left/Right Arrow). I currently have kubuntu 9.04 on my laptop, but I also tried with various other distros (live cd) including suse and there was everywhere the same problem, brightness hotkeys just didn’t work. After trying 100 other things I googled somewhere the solution, and that is, just put
to the file /boot/grub/menu.lst at the end of each line where kernel words are, simple as that if you know it Maybe this can be applied to some other laptops too. Have a nice day.
Thank you for the tip,but unfortunately it didn’t work for me. I have a Sony Vaio VGN-FS850. I added the line (via Yast–> Boot Loader) and no luck, nothing happens and I reboot the machine.
kernel /boot/vmlinuz-18.104.22.168-0.1-pae root=/dev/disk/by-id/ata-TOSHIBA_MK1031GAS_Z58P1118S-part5 resume=/dev/disk/by-id/ata-TOSHIBA_MK1031GAS_Z58P1118S-part4 splash=silent showopts acpi_osi=Linux
Well maybe other will have more luck. Thanks anyway.
