Has anyone managed to install any Linux distribution on Toshiba QOSMIO X870 3D that works reasonably well?
I tried Kubuntu, but have problems with video card. Shortly after the booting starts, the white screen starts flashing and all I can do is reboot. Any help would be much appreaciated. BTW, I also installed proprietary driver from NVIDIA web page, but nothing has changed.

Hi:

Welcome to Linux Questions!

I recently installed Fedora on my friends Toshibia laptop.
It works great but I didn't realize until after installing Fedora that the Toshibia laptop already had over-heating problems.

Depending on how old your Toshibia is; Ubuntu or Linux Mint might be a better choice.

Other members may have other suggestions for you.

Hope this helps

As Ztcoracrat said, if your laptop is old, you may want to install a lighter distro. However, I wouldn't reccommend Ubuntu or linux mint as a lightweight desktop environment. Rather, you should try Lubuntu, since it is lightweight. If your laptop is new, you should be able to use any distro that you want.

Or maybe give Puppy Linux a go--

Thanks for your replies. The fact is that Toshiba QOSMIO X870 3D is one of the newest laptops with Intel i7 4-core processor, so it's not a question whether it can handle KDE and it's heavy-weight applications or not. My problem was that the laptop was too new for any distribution to install flawlessly on it. In the end, I managed to install Kubuntu on it, but not before I booted it in Rescue mode, manually connected to wireless network and downloaded and installed the latest Nvidia drivers. Now it works perfectly, but the installation was pain in the ass.

Geeez! I feel your pain!

How come in Rescue Mode? Was it the only way?
If so; I understand how that was irritating!

I too have had some interesting install's to say the least--

I just went through a similar predicament myself.
Sometimes when you install 'new hardware' (depending on the distro) one has to jump thru a few hoops to keep what you have.

The folks at Ubuntu are pretty good with Lubuntu:

As far as I know, it was the only way. The problem was with Nvidia drivers and whenever Linux went into graphical mode, the screen began to flicker and the system became unusable. Rescue mode allowed me to access the system from the text mode, which of course worked fine and let me install the correct Nvidia drivers.

"Rescue mode" could well be the best way to install the nVIDIA drivers -- the other way is getting a terminal with Ctrl+Alt+F2* but depending on when the drivers are loaded this may not work.
Frankly, if you have a new machine then the nVIDIA procedure you went through is probably the least painful install you'll find. Please bear in mind that if you were to install Windows on a brand-new system you may well find you have to do pretty much the same as regards safe mode and drivers.
The good news is that in my experience once you've installed the drivers the pain is generally over and, should an errant update cause video problems, you already know how to solve them.

*I suggest this over the usual Ctrl+Alt+F1 because some distros place X on the first tty nowadays.

That's good news.

I'm so glad that there is a way around Nvidia! (drivers)
I keep this in mind for future practice.
