Linux On My Samsung

@ voRia: About the N510 brightness control issue: What we know: -The /proc/acpi/video/IGPU/LCD0 file exists, is not empty.The value inside it can be echoed and modified, without effect on the actual screen brightness. -The Fn/UP&DOWN keys do change in the same way the the current value contained...

Just to be sure I did not miss something: I added in the GRUB command line backlight_control=video instead of = vendor , as you mentioned only these two values are available for this variable.Updated GRUB &rebooted. It works as with quiet splash only in that command line: FN/UP&DOWN make the...

@AMvis, Int http://bbs.archlinux.org/viewtopic.php?pid=655144 apaige said on 5/11/2009 he was using NVIDIA driver 190.42.Fiveseven did not said which one he used. That's all was said about the NVIDIA driver in this thread, I think. I tried 4 NVIDIA drivers: 173, 185, 190 and 195. All four looked sta...

I have ben too logical and/or optimistic :eek: Then,why and how adding the correct wording acpi_backlight=vendor to quiet splash in the same GRUB command line is breaking the logical link between an FN/UP or DOWN keys action and the subsequent brightness bubble display?It's not logical, as it shouls...

hello AMvis, At last someone who gets the same troubles with his N510...I'm not that pleased reading it, but it shows some other people are also trying to have their N510 running with another OS than the standard one... Well I'm not really decided to give up for the time being...although I can't do ...

Tried the grub file edition ,adding acpi-backlight=vendor. It is worse than before ,as now the Fn/UP & DOWN do not let anymore the brightness bubble even appear on the screen, as they did before. I'm puzzled by the fact you are always speaking about backlight control, which is not the current is...

Sorry, I do not even understand your question, as I do not even know what a video kernel is.... And I do not know what is loaded or not at boot time, as I did not do anything to choose what happens (or not) at boot time: as long as the machine starts having chosen your 2.6.31-19 kernel, it's OK for ...

As an addition to the previous answer, I checked something just to see what happens..or not. When the Fn/UP &DOWN keys are used, the brightness value is indeed altered accordingly in the /proc/acpi/video/IGPU/LCD0/brightness file: 20 when DOWN to the minimum and 100 when UP to the maximum. So th...

First command lists what I understand to be the brightness possible levels, from 20 to 100 (by steps of 10 only) , and the current level reads : 80 Second command allows to change the current level I changed it to 20 in the command: current:20 is shown in terminal.The value has indeed been changed i...

Answer to "ls /proc/acpi/video" is:
