recently I installed debian 9.2.1 on my mac air 13（model a1466)
everything is ok except the keyboard has a little problem.
when I type the key[~](below the [esc]) in command line, the actal output is "<", I set the keyborad models to "Apple Laptop", seems no improvement..
So anyone knows how to fix it? Thank you
I found the solution on this #162083
sudo gedit /etc/modprobe.d/hid_apple.conf
add setting:options hid_apple fnmode=2
sudo update-initramfs -u
reboot

I have a dual-boot setup with Windows 10 and Kubuntu 18. Following instructions found from here and there I managed to get the Windows to run as guest in Kubuntu host as a VM using VirtualBox.
sudo usermod -a -G disk $USER
VBoxManage internalcommands createrawvmdk -filename "/path/to/vm/win10.vmdk" -rawdisk /dev/sda -partitions 1,3,4 -relative
The first line is to avoid running VirtualBox as superuser.
When I boot the VM, I briefly see an error message
Boot Failed. EFI DVD/CDROM
SystemBootOrder not found. Initializing defaults.
Creating boot entry "Boot0003" with label "ubuntu" for file "\EFI\ubuntu\shimx64.efi"
and then end up in grub shell. Now, when I run the commands
insmod chain
set root=(hd0,gpt1)
chainloader /EFI/Microsoft/Boot/bootmgfw.efi
boot
Windows boots and works just fine but entering these every time is not exactly smooth workflow. Any idea how to permanently fix this?
Please note that I'd still like to be able to physically boot into both OS's.
Thanks,
I had the same problem. I fixed it, but then updated my kernel and so grub re-un-fixed it for me! Figuring it out for the second time was quicker, but I figured it'd be even quicker next time to find my answer on StackOverflow!
My grub.cfg file in /boot/efi/EFI/ubuntu looked like this:
search.fs_uuid 47d6233f-c0ae-4f89-bf18-184452eac803 root hd0,gpt6
set prefix=($root)'/boot/grub'
configfile $prefix/grub.cfg
Because we have setup the VirtualBox vmdk file with only the selected partitions for Windows to work, the search.fs_uuid command was failing, $root was empty and so grub can't find $prefix/grub.cfg (/boot/grub/grub.cfg in my linux rootfs which is on sda6==gpt6)
I automated it by changing the EFI grub.cfg, note my EFI System partition is 2 not 1 as in your example:
search.fs_uuid 47d6233f-c0ae-4f89-bf18-184452eac803 root hd0,gpt6
set prefix=($root)'/boot/grub'
if [ -f $prefix/grub.cfg ]
then
configfile $prefix/grub.cfg
else
insmod chain
set root=(hd0,gpt2)
chainloader /EFI/Microsoft/Boot/bootmgfw.efi
boot
fi
Now if grub can find the cfg file it will give me the menu to select the boot as before, but if it can't - when I'm in VirtualBox - it'll just boot straight into Win10.
Hope this helps!
I am struggling to disable USB ports on macs with the new Yosemite
My original intention was to give read only access to USB drives but it seems impossible, so I decided to go for the complete removal of the USB access
I followed the instructions on the osX manual but won't work
I tried this, posted here in the forum: link but it won't work
What I get now is this error link
(kernel) Can't remove kext com.apple.iokit.IOUSBMassStorageClass; services failed to terminate - 0xdc008018.
Failed to unload com.apple.iokit.IOUSBMassStorageClass - (libkern/kext) kext is in use or retained (cannot unload).
It may be because I removed the file from the extensions folder first, but if that was the case, why usb is still working?
Hope you can help somehow.
Cheers
Unload it first with
kextunload /System/Library/Extensions/IOUSBMassStorageClass.kext/
However having said that removing and even deleting this kext in Yosemite doesn't seem to prevent USB working again on reboot. In fact you now lose the ability to unload the kernel extension once loaded.
I'd like to improve the previous answer but I cannot comment on it, so I will add it here.
I am having the same problem and to solve it I confirm that you should unload the driver with
kextunload /System/Library/Extensions/IOUSBMassStorageClass.kext/
In order to keep this setting at reboot, I added a call to the root crontab (since this won't be modified by updates nor other users)
to become root
sudo su -
modify root crontab
crontab -e
add the line to the file and close it
#reboot kextunload /System/Library/Extensions/IOUSBMassStorageClass.kext/
I hope this helps
You need to unload the AppleUSBCardReader and AppleUSBODD drivers as they load IOUSBMassStorageClass. Run the following commands in the terminal:
sudo kextunload -b com.apple.driver.AppleUSBCardReader <br>
sudo kextunload -b com.apple.driver.AppleUSBODD <br>
sudo kextunload -b com.apple.iokit.IOUSBMassStorageClass
No quick button does not work. The reason? Already search the entire Internet and found nothing. I was told that perhaps the problem in Ubuntu. We all know it works, but I have not. Who knows what?
Put the Russian keyboard layout above the English. Thanks LazyOne
Only this helped me to make Ctrl+C, Ctrl+X, Ctrl+V to work on Russian and English keyboard in RubyMine 7:
Download LinuxJavaFixes and put the contents of build folder to ~/LinuxJavaFixes/build
Add the following code to the RubyMine config file ..RubyMine-7.0.4/bin/rubymine64.vmoptions (for linux x64), or ..RubyMine-7.0.4/bin/rubymine.vmoptions (for linux x86):
-javaagent:/home/YOUR_USERNAME/LinuxJavaFixes/build/LinuxJavaFixes-1.0.0-SNAPSHOT.jar
Change YOUR_USERNAME to your system username.
This code helped me:
sudo add-apt-repository ppa:attente/java-non-latin-shortcuts
sudo apt-get update
sudo apt-get dist-upgrade
restart unity-settings-daemon
I installed Fedora 19 in windows 8 hyper-v and its working fine but there is one small problem with the display setting, as fedora 19 display setting not providing 1366x768, but i need to set the display to 1366x768 to view full screen, so any suggestions??
Open a Terminal (Ctrl-Alt-T)
Run
sudo vi /etc/default/grub
Find the line starting with GRUB_CMDLINE_LINUX, and add
video=hyperv_fb:[the resolution you want]
If the resolution I want is 1280×720 then my line ends up looking like this:
GRUB_CMDLINE_LINUX="… quiet splash video=hyperv_fb:1280×720"
Write the changes and quit vi by hitting ESC and typing
:wq
Run:
sudo grub2-mkconfig -o /boot/grub2/grub.cfg
or when installed in EFI mode
sudo grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg
Reboot the virtual machine
(Note: this is just an over-sized reply.)
I'm using Windows 10 and Fedora 26. Basically what Daniel said still holds, with some modifications:
The file /boot/grub2/grub.cfg doesn't exist on fresh install Fedora 26, and creating the file doesn't affect booting parameters at all (verified with /proc/cmdline). The correct file is /boot/efi/EFI/fedora/grub.cfg (I get the path from Fedora Wiki).
Not every resolution is supported: 1920x1080 is, 2560x1080 is not. Unsupported resolution is simply ignored. I ended up setting it 1920 although my monitor is 2560.
And finally an advice: back up everything you edit. You'll need it some day.
Update: still works in Fedora 27.
I think it's a limitation from Microsoft.

I'm trying to build a Webkit Kiosk on a Raspberry Pi.
I found a good start at: https://github.com/pschultz/kiosk-browser
The things I want to do:
1) Start the kiosk without logging in (with inittab?)
Peter Schultz pointed out adding the following line:
1:2345:respawn:/usr/bin/startx -e /usr/bin/browser http://10.0.0.5/zfs/monitor tty1 /dev/tty1 2>&1
But he did not explain the steps to make this work (for noobs).
What I did is add his code to a personal git repository and cloned this repo to /usr/bin/kiosk and sudo apt-get install libwebkit-dev and sudo make.
The line to add to inittab will be:
1:2345:respawn:/usr/bin/startx -e /usr/bin/kiosk/browser http://my-kiosk-domain.com tty1 /dev/tty1 2>&1
If I do this, I generate a loop or some kind...
If you want to automatically load a browser full screen in kiosk mode every time you turn on the rpi you can add one of these two lines to the file /etc/xdg/lxsession/LXDE/autostart
#chromium --kiosk --incognito www.google.it
#midori -i 120 -e Fullscreen -a www.google.it -p
The first is for chromium and the latter is for midori, the rpi default lightweight browser.
Hint : Since we will use the rpi as a kiosk we want to prevent the screen from going black and disable the screensaver. Edit the autostart file:
sudo pico /etc/xdg/lxsession/LXDE/autostart
find the following line and comment it using a # (it should be located at the bottom)
##xscreensaver -no-splash
and append the following lines
#xset s off
#xset -dpms
#xset s noblank
Save, reboot.

The upvoted answer suggest to run LXDE for it. You could also do it without such a heaver desktop enviorment. You could just start midori or chromium in an X session:
xinit /usr/bin/midori -e Fullscreen -a http://www.examples.com/
xinit chromium --kiosk http://www.examples.com/
Sometimes Fullscreen mode of midori is not working as expected and midori is not using whole screen. In these cases you could map it inside a very simple window manager like MatchBox to get real fullscreen. Due to xinit you have to wrap everything in a shell script.
#!/bin/sh
matchbox-window-manager &
midori -e Fullscreen -a http://dev.mobilitylab.org/TransitScreen/screen/index/11
Autostart could be done simply be using /etc/rc.local.
More information concerning screensaver issues and an automated restart could be found here: https://github.com/MobilityLab/TransitScreen/wiki/Raspberry-Pi#running-without-a-desktop
Chromium has a dependency problem on some debian derivate for arm architecture. For Cubian you find the bug report here. I am not sure if you could install chromium on latest Raspbian without problem.
But I really could recommend midori. It's very fast and support for modern web technologies is very good. As Chromium it is using webkit as rendering engine. If you miss some html5 / css3 features consider an update of libwebkitgtk (for example by using package of debian testing).
It's possible you haven't set the DISPLAY environment variable.
Try:
export DISPLAY=:0
/usr/bin/startx /usr/bin/browser
Or, browser can also take a display argument (so you don't need the environment variable):
/usr/bin/startx /usr/bin/browser :0
This works for me on Raspbian from a standard terminal shell (I'm logged in over SSH).
Updated for the current version of Raspbian (with Pixel desktop) install with noop 2.0.
I found you need to edit in two different places to get it to work.
/etc/xdg/lxsession/LXDE/autostart
/home/pi/.config/lxsession/LXDE-pi/autostart
So my configure file is:
# #xscreensaver -no-splash
#xset s off
#xset -dpms
#xset s noblank
#chromium-browser --kiosk --incognito http://localhost
And that's it.
You should probably start with checking if /usr/bin/kiosk/browser is working at all. You should start normal X session (graphical environment) on your RaspberryPi, launch terminal, try running this command:
/usr/bin/kiosk/browser http://my-kiosk-domain.com
and see what it prints on the terminal. Is this working? Do you see any error messages?

I think Instant WebKiosk for Raspberry Pi could be useful for you.
