** Description changed: As advised in bug #645624 I open a new bug on this issue. I just performed a complete format and fresh installation of 11.10 and the keys used to adjust the screen birghtness still don't work. The keys I use are : Fn + arrow up = increase brightness Fn + arrow down = decrease brightness Fn + F5 = toggle backlight I also noted that Fn + F9, wich should toggle the wifi network adapter, does not work also. It look like bug #296489 but I'm not sure. I have still to experience the flickering effect mentioned in bug 810093 so I think it's not the same bug. It's always reproducible. Proposed solution: The samsung-laptop module is not loaded automatically since the kernel fail to identify the platform it run on. I think this issue is the one described in bug #36082 on the kernel bugtracker (can't access it atm, I think the bugzilla has yet to be restored). The fact is that the N2320 netbook identify itself as N150/N210/N220/N230 but the three other N150, N210 and N220 identify themselves as N150/N210/N220 only. This is confirmed by running modprobe samsung-laptop, which result in : FATAL: Error inserting samsung_laptop (/lib/modules/3.0.0-12-generic/kernel/drivers/platform/x86/samsung-laptop.ko): No such device Also the samsung-laptop module is not in the lsmod result. (cf. attachement). The patch I send, look at the previously mentioned kernel ticket, fixed this issue for me but I wasn't able to test the control back then. This patch have been pushed to stable few days ago. + --- + AlsaVersion: Advanced Linux Sound Architecture Driver Version 1.0.24. + AplayDevices: + **** List of PLAYBACK Hardware Devices **** + card 0: Intel [HDA Intel], device 0: ALC269 Analog [ALC269 Analog] + Subdevices: 1/1 + Subdevice #0: subdevice #0 + ApportVersion: 1.23-0ubuntu4 + Architecture: i386 + ArecordDevices: + **** List of CAPTURE Hardware Devices **** + card 0: Intel [HDA Intel], device 0: ALC269 Analog [ALC269 Analog] + Subdevices: 1/1 + Subdevice #0: subdevice #0 + AudioDevicesInUse: + USER PID ACCESS COMMAND + /dev/snd/controlC0: thomas 1438 F.... pulseaudio + CRDA: Error: [Errno 2] Aucun fichier ou dossier de ce type + Card0.Amixer.info: + Card hw:0 'Intel'/'HDA Intel at 0xf0400000 irq 47' + Mixer name : 'Realtek ALC269' + Components : 'HDA:10ec0269,144dc072,00100004' + Controls : 14 + Simple ctrls : 9 + DistroRelease: Ubuntu 11.10 + HibernationDevice: RESUME=UUID=7575c539-0444-4ef0-9021-5c6bd28ce73d + InstallationMedia: Ubuntu 11.10 "Oneiric Ocelot" - Release i386 (20111012) + MachineType: SAMSUNG ELECTRONICS CO., LTD.
