Bluetooth

Configure Bluetooth by following instructions found in the Bluetooth article.

Laptop sound on TV with HDMI cable

Emerge the media-sound/pavucontrol utility if laptop has a sound output problem with HDMI cable, it helps to configure sound through HDMI cable.

Kernel configuration

To build a custom kernel configuration, it is helpful to get output with console: lspci -nn (lsusb) and lspci -k. Use any bootable Linux LiveCD for that. There is [vendor id:device id] (for example, see lspci -nn above, 00:16.0 Communication controller [0780]: Intel Corporation 5 Series/3400 Series Chipset HECI Controller [8086:3b64]) and kernel driver (for example, see lspci -kk above, Kernel driver in use: mei_me ) information. It is easy to find which kernel modules need to be set with [vendor id:device id] and kernel driver. Use search in Internet or kernel documentation.

Troubleshooting

Graphics card. Problem with 100% brightness after reboot

How to install graphics driver described (see, Gen5) in the Intel article.

Laptop does not remember brightness, after rebooting it sets brightness to 100%

Workaround

Install xbacklight (for xf86-video-intel only):

root #emerge --ask x11-apps/xbacklight

or acpilight (Modern replacement which uses kernel interfaces)

root #emerge --ask sys-power/acpilight

Create udev rule to save brightness

FILE /etc/udev/rules.d/91-backlight.rulesudev event to save brightness
# Storing brightness
ACTION=="change", SUBSYSTEM=="backlight", RUN+="/bin/sh /etc/backlight.sh"

Create scripts to save and restore actual brightness:

FILE /etc/backlight.shScript to save brightness
#!/bin/sh
#It saves actual backlight percentage to /etc/backlight
brightness=`cat /sys/class/backlight/acpi_video0/actual_brightness`
brightness_max=`cat /sys/class/backlight/acpi_video0/max_brightness`
brightness_out=$(((100000/brightness_max*brightness+500)/1000))
echo $brightness_out > /etc/backlight

This script need to be added to startup, for example /bin/sh /home/user/Scripts/brightness.sh, run it as user:

FILE /home/user/Scripts/brightness.shScript to restore brightness on startup
#!/bin/sh
brightness=`cat /etc/backlight`
xbacklight -set $brightness

Apply udev 91-backlight.rules with:

root #udevadm control -R

Read-only SD-Card

It found that sometimes SD-card with non-locked switch recognized as read-only after it inserted [1]

Workaround

Install [Hdparm]]. Use console commands to remove read-only attribute before mounting sd-card partition:

root #emerge --ask hdparm
root #hdparm -r 0 /dev/mmcblk0
root #hdparm -r 0 /dev/mmcblk0p1

For example, the following script remounts a SD-card as read-write (rw). You need to correct mount_options and xuser (user name) to adapt the script for your needs. It needs to run script after sd-card mounted. udisks-glue can be used to start this script automatically.

FILE sdcard-mount-fixChanging sdcard mount from RO to RW
#!/bin/sh
export PATH=/bin:/sbin:/usr/bin:/usr/sbin
sdcard=`mount | grep mmcblk0p1`
if ! grep -q mmcblk0p1 <<< "$sdcard" ;then
	exit 0
fi
if grep -q rw <<< "$sdcard" ;then
	exit 0
fi
logger -i "$sdcard"
logger -i "Fixing that sdcard mounted as read-only"	
cd /dev/disk/by-uuid/
for entry in *
do
  linktext=`readlink $entry` 
  if  /bin/grep -q mmcblk0p1 <<< "$linktext" ;then
		hdparm -r 0 /dev/mmcblk0 2&>1 >/dev/null
		hdparm -r 0 /dev/mmcblk0p1 2&>1 >/dev/null
		xuser="tester"
		mount_options="nodev,nosuid,uid=1000,gid=100,shortname=mixed,dmask=0077,utf8=1,showexec,flush,uhelper=udisks2"
		mount -o remount,rw,$mount_options /dev/mmcblk0p1 /run/media/$xuser/$entry
		mountresult=`mount | grep mmcblk0p1`
		logger -i "sdcard mounted as $mountresult"
  fi 
done

VAIO key (Vendor key) does not work

VAIO key has keycode 360. X does not support keycodes are greater than 255.

Workaround 1

It needs to remap VAIO key to make it works with XFCE (probably Gnome, KDE) to bind it in order to start script or application with VAIO key.

Create /etc/udev/hwdb.d/61-keyboard-local.hwdb:

FILE /etc/udev/hwdb.d/61-keyboard-local.hwdbEvent creation for VAIO key
# sony-laptop driver
keyboard:name:Sony Vaio Keys:dmi:bvn*:bvr*:bd*:svnSony*:pn*
 KEYBOARD_KEY_3b=prog4                                  # VAIO

Update the database as described here and reboot the PC.

Workaround 2

Other method is to edit include/uapi/linux/input-event-codes.h kernel file. It needs to change KEY_VENDOR keycode from 360 (0x168) to keycode with value less than 255.

Example, swiping KEY_CHAT and KEY_VENDOR:

Create /usr/src/linux/input-event-codes.h.patch:

FILE /usr/src/linux/input-event-codes.h.patchKEY_VENDOR patch
--- a/include/uapi/linux/input-event-codes.h	2016-01-11 08:01:32.000000000 +0900

Apply it with:

root #patch -p1 < input-event-codes.h.patch

Then recompile kernel, reboot PC.
