Laptop screen shutting down when using Chromium

Philip Harrington · **Joined:** Fri Oct 23, 2015 7:37 pm **Posts:** 1

I have just installed Uberstudent as of 22.10.2015, using the current archive and am having a fairly serious problem with Chromium. Every time I go into the Themes or Extensions archive page in the browser, the laptop screen shuts down immediately. I already have the most current updates available so I have no idea what to do - other than not opening that particular part for browser extensions.

Any help would be appreciated.

The laptop is an L300 Toshiba its about four years old but still seems pretty competent with the OS.

By "archive page(s)" do you mean...
chrome://settings > Appearance > Get themes > https://chrome.google.com/webstore/category/themes
chrome://extensions > Get more extensions > https://chrome.google.com/webstore/category/extensions

What happens if you click on those Google.com/webstore links above?

Do you mean the entire screen goes black? Is the whole system crashing?

I'm also experiencing this issue. Chrome makes the screen go black. There is still audio when there's music or a video playing, but the screen is black and unresponsive.

Please go to Applications menu > System > Software > Driver Manager and run the program. Does it recommend a driver to you? What driver does it say you are using?

Thank you. The driver manager neither suggests any drivers nor lists any. The window says no propriety drivers are in use.

I need to look at your computer's hardware and the drivers in use and the version of xorg that is installed. Please go to Applications menu > Hardware > System Profiler and Benchmark, run the program and save the snapshot to your desktop, and attach the file here. Alternately, you can copy and paste the contents to pastebin.com and set it to expire in a day or two and then post the link here. Where we'll probably end up going is to have you either update or downgrade your xorg server stack.

I'm pretty sure you're dealing with this bug. Let's first try upgrading the xorg server stack for your i915 Intel Graphics. To do that we're going to:

(1) Add the uberstudent.net heraclitus-backports repository to your machine (which is already present on your machine but not enabled, since your system is one that has been upgraded from 4.0 or 4.1 to 4.3)
(2) Update the repository info on your machine
(3) Install the new packages.

Please open a terminal and run the following lines, one line at a time:

Code:

sudo cp -fv /usr/share/uberstudent/uberstudentsources/heraclitus/* /usr/share/uberstudentsources/heraclitus
sudo cp -fv /usr/share/uberstudentsources/heraclitus/official-package-repositories.list /etc/apt/sources.list.d
sudo cp -fv /usr/share/uberstudent/uberstudentsources/overwrites/preferences-heraclitus /etc/apt/preferences
sudo apt-get update
sudo apt-get -s install --install-recommends linux-generic-lts-vivid xserver-xorg-core-lts-vivid xserver-xorg-lts-vivid xserver-xorg-video-all-lts-vivid xserver-xorg-input-all-lts-vivid libwayland-egl1-mesa-lts-vivid 

Then, reboot and let me know if this fixes the issue. If not, we'll proceed to add a few lines to your 20-intel.conf file.

Went through those steps. Got the following popup when I rebooted:

Software index broken
This is a major failure of your software management system. Please check for broken packages with synaptic, check the file permissions and correctness of the file '/etc/apt/sources.list' and reload the software information with: 'sudo apt-get update' and 'sudo apt-get install -f'.

I also keep receiving this message:

The package uberstudent-desktop-xfce is not currently installed on your system. This means that several new features that are part of UberStudent 4.3 'Heraclitus' could not be installed on your system during the recent upgrade. The new features include several new Xfce panel plugins you can add to your panel and improved driver support.

Re-installing uberstudent-desktop-xfce will install the new features, as well as restore the default set of software to your system, including any software you chose to remove since you installed UberStudent.

Would you like to re-install the package uberstudent-desktop-xfce?

But when I try to get it to re-install I get the same message as above.
