What does your > manual say about hardware control of screen brightness? > > There are reported cases of problems with brightness control in F11 - eg Samsung NC-10 brightness control does not work under battery power - and you need a setpci command to set the brightness directly - the OP did not report which hardware this applies to in this case but this may be a different example where there is a problem also. In the thread at http://fedoraforum.org/forum/showthread.php?t=226597 in post #5: it says for the NC-10 you need "setpci -s 00:02.1 F4.B=XX" where XX is a hex number from 00 to FF" I have an NC-10 and confirm that this is the case for me. Would be useful to know if there are other BZ for this problem also? -- View this message in context: http://www.nabble.com/Battery---Control-Screen-brightness-tp25424165p25426988.html Sent from the Fedora List mailing list archive at Nabble.com. -- fedora-list mailing list fedora-list@xxxxxxxxxx To unsubscribe: https://www.redhat.com/mailman/listinfo/fedora-list Guidelines: http://fedoraproject.org/wiki/Communicate/MailingListGuidelines
