I changed everything according to you post, Yu Kei, but my screen still stays black - I am using 13.10 x64 on Yoga 11s. I did run grub-update, btw. Would be more than happy to get help. Sad not being able to use this great device without another screen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1217861 Title: black screen while trying to test ubuntu 13.10 on lenovo yoga 11S To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1217861/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Hi Hugh, I don't know if you have been successfull with the display. If you start Ubuntu (USB-stick) and the bottom icon appears, press "Esc" to enter the menu, press F1 for Help and F6 for bootoptions. Press "Esc" again to leave the help. At the bottom you see a commandline. You cursor is behinder the ...splash quiet -- Now type "i915.invert_brightness=1" and enter to start Ubunut. Your display shouldn't turn off. If you have already an installation type "e" at the boot menu at the following lines identify the "...splash quiet" thing an type the above parameter behind it (i915.invert_brightness=1) and start the system. As root and with an editor (I use MC) change the grub file at /etc/default.d/ change: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i915.invert_brightness=1 acpi_osi=Linux acpi_backlight=vendor" save the file and run "sudo update-grub". Don' forget the last. To prevent the black screen when recovering from Sleep mode create a file xorg.conf at the folder /etc/X11. The contence should be: Section "Device" Identifier "Card0" Driver "intel" Option "AccelMethod" "sna" Option "Backlight" "intel_backlight" Endsection Thats it, at least for the screen. I'm working on the rest and maybe doing a tutorial or something else. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1217861 Title: black screen while trying to test ubuntu 13.10 on lenovo yoga 11S To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+bug/1217861/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1217861] Re: black screen while trying to test ubuntu 13.10 on lenovo yoga 11S
Update: Work around for yoga 11s backlight problem during/after ubuntu 13.04 installation. Given that the blacklight for the laptop screen is turned off when the live USB stick boots to do the installation I figured I'd just use a different screen. So I attached my TV via an HDMI connection and switched my TV input to that source. This does permit the laptop screen to activate. By selecting the install ubuntu option in the BIOS and entering ubuntu installation program I first tried to install ubuntu along side the windows 8 (that came stock). To do so I tried to partition the hard drive (SSD) in half, one for windows and one for ubuntu. The ubuntu installation nearly completed, but failed due to some error with the GRUB. I don't know what the GRUB actually does, but I gather it's important for booting up a particular operating system. There was a notification of some problem using a hard drive in some format (GPT? GTP? don't know). Given this failure of ubuntu and my complete lack of faith in microsoft products, I went ahead and committed to ubuntu. So now I retried the installation erasing W8 completely, which was successful. After the installation and after the log-in I shut the laptop So I updated OS as completely as possible and then started to get crazy. I turned off the TV display in the settings>displays control panel and lo and behold, the laptop display remained on. Upon reboot without the TV HDMI connection, the laptop screen does not work, as before. So I figured out if you shut the laptop screen and reopen it, the display flashes some commands (in the BIOS maybe - black screen withonly text), then redisplays the ubuntu desktop log-in screen. >From this point, the screen works until you reboot the laptop. The brightness keys only serve three functions: F9 turns off screen (as it should), F11 (brightness-) turns brightness down, but F12 (birghtness+) only turns the brightness up one notch. That is to say, the display flips from almost off to all the way on. Not quite nuanced, but it works. Additionally, I still don't know how to apply the advice in the link to debian instuctions above. How do I modify the kernel as instructed by Gordon Harris (above). Do I just open the (is there only one?) kernel in a text editor and add: i915 invert_brightnesss=1. Do I need to recomplie (I think this was suggested in other articles when modifying the kernel. Then run the echo options command in the terminal??? Additional issues: Any good links for ways to make the tablet mode activate properly? The touch screen also moves the cursor, but doesn't always do any clicking? Any good links for dealing with this? The touchpad tap to click option works fantastically, but the actual clicking is tricky and moves the cursor too much when you touch to push the button. Articles people? The touchpad shut off in folded (tablet) mode also does not work. Any links to fixes? The display brightness control needs resolving. Will this be fixed after I get the invert_brightness thing resolved? I haven't checked the bluetooth, but the symbol does not show up next to the time, battery icon and cloud.

[Bug 1217861] Re: black screen while trying to test ubuntu 13.10 on lenovo yoga 11S
I have this problem with my yoga 11s while trying to install both 13.04 and 12.04. I can see that ubuntu has loaded if I tilt the screen in the light and can hear the ubuntu start up noise(and volume up/down noise) but the backlight on the screen is off. I am working with the .iso's and only have Windows 8 on my machine. It looks like the solution above is for someone capable of modifying the kernels using the command line. I don't even know how if W8 has a command line? and do not wish to install 13.10 yet. Is there anyway to fix this for 13.04?
