The samsung-laptop driver fails to load on my laptop (N150), due to a DMI mismatch: the driver expexts N230 to be in the identifier (and product/board name), whereas my laptop only includes N150/N210/N220. Full DMI output is attached.
Created attachment 59742 [details] Hack to allow driver to load without force=1 This is just a quick patch I put together to verify there weren't any other issues with the driver on my laptop (there weren't). It simply removes N230 from the DMI identifier, allowing the driver to be loaded without force=1.

I have a Samsung netbook N210 and the samsung-laptop driver failed to load: [root@localhost ~]# modprobe -v samsung-laptop insmod /lib/modules/3.0.0-desktop-0.rc7.2.1.mga2/kernel/drivers/platform/x86/samsung-laptop.ko.gz FATAL: Error inserting samsung_laptop (/lib/modules/3.0.0-desktop-0.rc7.2.1.mga2/kernel/drivers/platform/x86/samsung-laptop.ko.gz): No such device The symptoms are very similar to those described by Daniel Eklöf and I think we encoutered the same issue. Dmidecode output attached. (On a side note, even if I load the driver with force=1 the brightness keys don't work but I can set the brightness by writing "1" or "8" several time to /sys/class/backlight/samsung/brightness. I'm still trying to figure out where this issue is from.)
