I have an older laptop and want to hook it to a TV that has USB, HDMI, and standard (F-connector) cable. Laptop has USB, and VGA. Can I just get a USB to USB cable and it will work, or do I need a USB Display Adapter? Thanks again.Xubuntu 20.04.
I have a Sony vaio laptop fit 15E model SVF1521DCXW and I want to turn OFF its keyboard back-light. It doesn't have a phisycal function shortcut key on the keyboard . I can turn off it with VAIO Control Center in Windows OS but I don't know how can I turn it off in Ubuntu 14.04.
I get SVF1521DCXW by running sudo dmidecode -s system-product-name.
First of all doesn't exist /sys/devices/platform/sony-laptop/kbd_backlight file on my machine.
By default, keyboard backlight is stay OFF; When I press any key it turns ON for a while 15 seconds and if I don't touch any key, it goes to turns OFF again.
Important: All try had same result on battery and AC power
The ls -l /sys/devices/platform/sony-laptop/ command shown files/directoes/symbolic links as following (I removed extra attributes and highlighted type of them into [ ]. All of them are root owner.):

Same output ^^ if run modinfo sony_laptop(Note: underscore_ instead of dash-)
What I tried are as following:
1. Reloading modprobe module with passing following commands:
sudo modprobe -r sony_laptop # <- No output. back to command prompt. And with -l option I get modprobe: invalid option -- 'l'
sudo modprobe -v sony_laptop kbd_backlight=0
Output of second command in above:(for both trying with sony_laptop and/or sony-laptop. also I changed kbd_backlight=0 to kbd-backlight=0 and I get no error and gave me the below output)
insmod /lib/modules/3.13.0-35-generic/kernel/drivers/platform/x86/sony-laptop.ko kbd_backlight=0
Result: No changes.
2. Reloding modprobe module with passing this command:
sudo modprobe -v sony_laptop kbd_backlight_timeout=3 kbd_backlight=0
Output: Nothing.
So I tried all things from this thread.
Result: No change.
3. ls -l /sys/class/leds
Output: total 0 (actually Nothing)
4. Trying to founding file
cat /etc/modprobe.d/sony-laptop.confcat /etc/modprobe.d/options.confcat /sys/class/leds/smc::kbd_backlight/brightness
Output: No such file or directory.
Expande option 1 from step 4: I create a file named sony-laptop.conf in /etc/modprobe.d and added options sony-laptop kbd_backlight=0 to the file, save it and restarted the computer. It doesn't work(even if I don't reboot), and I removed the file from there.
Expande option 2 from step 4: I create a file named options.conf in /etc/modprobe.d and added options sony-laptop kbd_backlight=0 to the file(Yes options command is part of command here), save it and restarted the computer. It doesn't work(even if I don't reboot), and I removed the file from there.
Expande option 3 from step 4: I already mentioned in step 3, I don't have any file there ;)
Result (for all options): Nochange
5. Trying to install some suggeted package on many sites:
sudo apt-get install nvidia-bl-dkms pommed
Output: E: Unable to locate package nvidia-bl-dkms
And if it helps I added that: part of lshw command:

Under Microsoft Windows 8, our Sony VAIO Tap 20 (a touch-screen desktop computer) automatically displays an on-screen keyboard if one touches a text field on-screen or there is otherwise no keyboard available (for example, the included bluetooth keyboard is switched-off or flat)... There is also a (notification area/system tray-based) option to display or hide the on-screen keyboard on-demand.
Does such functionality exist under Ubuntu 14.04 LTS ("Trusty Tahr")?
My understanding is that Ubuntu 14.04 LTS ("Trusty Tahr") is supposed to be a mostly smartphone/tablet-focused upgrade... But for the life of me, I cannot find functionality that replicates that of Windows 8 (as described above)!
I've finally convinced the wife to let me single-boot Ubuntu on our VAIO Tap 20, but the included bluetooth keyboard smashes through batteries like they're going out of fashion, so until we can buy a corded keyboard, we need a solution (preferably built-in) that replicates the functionality found under Windows 8...
--
Never mind - all one needs to do after @Rmano 's solution is log-out and log back in... I should also note that this was already installed under Ubuntu 14.04 LTS ("Trusty Tahr").
Tried searching but no one has this model/series it seems. Anyone know of any working touchscreen drivers for the VAIO VPCL2XXX series desktop all in ones?
Device is NextWindow Voltron
I have problem with my Sony Vaio Z VPCZ1. It has physical selector of GPUs which Linux kernel does not detect.
So after GRUB I see black display (I tried different distributions of Ubuntu and other Linux OS). I read in Ubuntu 10.10 was solve same problem with hybrid graphics but not in my case
I found solutions (not easy at do) for oldest models.
PS. for more information I found different webs: https://docs.google.com/document/edit?id=1DxDty2YGNJwq_I8zmVZxDMMXBP6g4HjaDjLfVfTs034&hl=en&pli=1
Update (2011.04.30): I tried update to Ubuntu 11.04 on my VPCZ11C5E and all work (without any patch) fine less Intel GPU (only works Nvidia).
