I installed ubuntu 16.04 LTS a week after official release using the mini ISO, then ubuntu-desktop without recommended packages. Since then, just installing packages on a need to basis.   After trying to wake the computer from sleep by using the touchpad, the light on the power button stops blinking and I hear the sound of the hard drive coming online. But :    the screen stays completely off, no backlight. the laptop doesn't respond to any keyboard presses. Everytime I use The magic SysRq to restart the laptop. Long pressing the power button works too.   This problem wasn't present when using ubuntu 14.04 LTS  The proposed solutions in all the possible duplicates on this website didn't solve my problem. One big difference is that my laptop screen is off not just blank.  Possible helpful informations. All got after system reboot.

Mac OS X 10.6.4, MacBook Pro, Apple Magic Trackpad.  The trackpad is unresponsive. Right-clicking on the Bluetooth icon in the menu bar shows me gray text that says "Bluetooth not available".  I don't see a system preference item in which to fight with this, but I don't see anything relevant.

I have found that there is a large community suffering from the problems with the WiFi-Bluetooth card Ralink RT-3290. It has been a problem since 2012-2013.  None of the solutions I've found is simple, effective and durable.  I managed, with great effort, some results. But when there is a kernel update, the problems return.  Can anyone provide a simple , effective and lasting solution? Is there a project from Ubuntu's developers to attack the problem?

I am having major issues with Ubuntu touchpad on a Dell Latitude 3570 Laptop.  If I use a USB mouse, everything works fine, but if I use a touchpad it is very hard to control.  For example, if I want to click on something that is in the middle of the screen, I click, but for some reason Ubuntu THINKS I have clicked at the bottom Left-Hand corner of the screen, and thus opens the rubbish bin.  It is REALLY making me angry.  I read somewhere that the following changes to synclient would fix it:  synclient FingerLow=9 synclient FingerHigh=10   These don't work.  And in any case as soon as I reboot the machine, synclient resets back to defaults (FingerLow=25, FingerHigh=30), so even if they did work I would have to set them every time I rebooted the machine!  Is there anything else I can try?  This is driving me insane.  For the sake of my sanity, please help me before I smash up my laptop.

We just bought a Lenovo  (which is supposed to have the Intel 8265 for wireless). This laptop was bought in part because it is certified to run Ubuntu and as such to me at least it would make sense for things to work out of the box... but no such luck.  First, I installed Ubuntu 17.10 and after installation realised Wi-Fi was not working. I also tried Ubuntu 16.04 from a USB drive since that is the version of Ubuntu it is certified for, but no luck there either.  The wireless chip is not detected by lshw (or even lspci by the looks of it), ip link does not show a wireless interface, and the iwlwifi kernel module is not loaded at boot (I can load this myself using modprobe iwlwifi but this does not make Wi-Fi work). I think it is a combined Wi-Fi/Bluetooth chip, and Bluetooth does appear to work (or at least Bluetooth shows up in Gnome and rfkill list).  modinfo iwlwifi | grep 8265 shows me a file ending in -34 is supposedly loaded but only a file ending in -33 (and some other lower numbers) is present in /lib/firmware, if that helps).  I have also installed the Linux 4.14.9 kernel in an attempt to get things to work, but this did not resolve the issue either.  Further information  root@ThinkPad-E570:~# modinfo iwlwifi | grep 8265 firmware:       iwlwifi-8265-34.ucode root@ThinkPad-E570:~# rfkill list all 0: tpacpi_bluetooth_sw: Bluetooth     Soft blocked: no     Hard blocked: no 1: hci0: Bluetooth     Soft blocked: no     Hard blocked: no root@ThinkPad-E570:~# dmesg | grep iwl root@ThinkPad-E570:~# lspci -nnk | grep 0280 -A3 05:00.0 Network controller [0280]: Realtek Semiconductor Co., Ltd.

Sigh. Same problem stands, however, just with a crappier wireless chip.

I have tried to update and upgrade my packages, and I have also followed  guide, but without success.

Hi my problem is exactly as the title says, Im planning to buy a bluetooth(4.0) dongle so I could use my  again. But to play it safe, I need to know first if it would realy work before going to the store.   And I'd like to know if there are disadvantages from using bluetooth as a reciever. like if there are delayed button response or smaller signal radius or frequent unresponsiveness.  Thank you.

I have a Lenovo G40-70 laptop, which comes with RTL8723be driver.  I'm using Ubuntu 14.04 LTS (with Kernel 3.16.0-38-generic), but this bug also occurs in 14.10 and 15.04.  Even with options rtl8723be fwlps=0 ips=0, the problem is not fixed yet. Wireless is unstable, lots of websites keeps loading forever and Ping command frequently shows data loss. It's very annoying. :(  BIOS version is the latest.  Blacklisting ideapad_laptop also doesn't work.  Sorry my english and thank you!

I recently updated my Lenovo Y50 computer to 16.04. Since the update, I have been unable to see or connect to any wireless networks. The output of running sudo lshw -C network is:     *-network UNCLAIMED          description: Network controller          product: BCM4352 802.11ac Wireless Network Adapter          vendor: Broadcom Corporation          physical id: 0          bus info: pci@0000:08:00.0          version: 03          width: 64 bits          clock: 33MHz          capabilities: pm msi pciexpress cap_list          configuration: latency=0          resources: memory:d1600000-d1607fff memory:d1400000-d15fffff   The fact that the wireless network controller is unclaimed leads me to believe that this is a driver related issue. I have checked and made sure that "Use proprietary driver" is checked in System Settings > Software &amp; Updates > Additional Drivers and I have run sudo apt-get install --reinstall bcmwl-kernel-source I have also restarted after every driver change to finish the changes.

Yesterday I installed Ubuntu 12.04 for the first time (I've always been a Windows user) as I was at the office and I had the Ethernet connected. At home I only use WI-FI. When I started Ubuntu it didn't connect or try to connect with any network. By google, I found the command rfkill and these are the results: 0: hci0: Bluetooth     Soft blocked: no     Hard blocked: no  1: brcmwl-0: Wireless LAN     Soft blocked: no     Hard blocked: no  2: dell-wifi: Wireless LAN     Soft blocked: yes     Hard blocked: yes  3: dell-bluetooth: Bluetooth     Soft blocked: no     Hard blocked: no  Well, the WI-FI is blocked by hardware, so I tried the command rfkill unblock 2 and it didn't work. As I didn't know even my Broadcom model, I found lspci and the result for the WI-FI is: 0e:00.0 Network controller: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01)  My laptop is a Dell Vostro 1520 with WinXP also installed. Thanks for the help! PS: It also may help that when I enter System Settings &gt; Network (it may be different, my Ubuntu is in Spanish) &quot;Airplane Mode&quot; is connected. When I try to unlock it, it goes to its original place after I close that window and open it again and when I reboot.  Update added from comment to an answer The Broadcom &quot;Additional Drivers&quot; are turned on and enabled.

The wireless drivers for the RTL8723DE appeared for downloading and the module is now usable for Wi-Fi.   See   But the bluetooth part of it is yet not supported on Ubuntu.
