Arbeit, Sonstiges, Uni Sony Vaio VPCZ11 with Kubuntu Oneric Posted on 20. October 201111. January 2015 by Michael Schramm in Arbeit, Sonstiges, Uni Everything works except keyboard backlight. But this can be reenabled by calling: sudo sh -c ‘echo 1 > /sys/devices/platform/sony-laptop/kbd_backlight’ Share:Click to email a link to a friend (Opens in new window)Click to print (Opens in new window)Click to share on Facebook (Opens in new window)Click to share on Twitter (Opens in new window)Click to share on Pocket (Opens in new window) Related
WIFI doesn’t work as it should anymore, it’s incredibly slow! This worked for me: sudo ifconfig wlan0 down sudo rmmod -f iwlagn sudo modprobe iwlagn swcrypto=1 sudo ifconfig wlan0 up It disabled hardware encryption of the WIFI chip, which is broken in the current driver. To make these changes static just run the following command: sudo sh -c ‘echo “options iwlagn swcrypto=1” > /etc/modprobe.d/iwlagn.conf’ LikeLike Reply
