M4800 Owners : Linux Problems. Finding Drivers.

Hi, i've read on the fedora forum that fedora 20 DVD just boots to a blank screen,

do you have any hints etc how yyou got the drivers from nvidea installed in your setup?

cheers.

 

I haven't tried fedora 20. But based on my experience on archlinux, after installation, I have to blacklist the open source N-card driver before booting.

Code:

~$ cat /etc/modprobe.d/blacklist.conf 
blacklist nouveau

After that, one can install bumblebee to get the Nvidia card work.

If the live DVD doesn't boot at all, it may not be a driver issue. You may also like to have a look at the boot method (grub-mbr v.s. EFI).

 

Hi, so my m4800 is inbound. when it gets arrives i'll give fedora 20 a go

quick look around for ideas gives me.

enable kernel options on the livecd (before install) >>>add nomodeset

or create my own live CD with nvidea drives allready installed, N-card driver blacklisted

or boot method, some post detail stuff to do...

or use arch. hehe.

cheers

 

hi, so fedora 20 boots to black screen.
requied to add nomodeset option before booting the live cd
after install this option carries over.
the nvidia drivers are aviable from the rpm repos, work fine for me, not required to manully blacklist the nouveau drivers
these work to but only at low resolution (nouveau)
no lower resolution can be selected.(nvidia drivers)
full sceen woks fine for me.
trackpad 'jitters', not a issue for me as i hate those things anyway, maybe i'll look for drivers, maybe not
all in all, it's great.
the internal SSD seems to have a have a speed of 0.15GB/s for copying a file to it's self.
the screen is great.

nice

 

I also had this problem (with M6800). There is a workaround at #3 of the following thread. But it will be greatly appreciated if you have a better solution and share it.

This is by far the only problem I have with M6800 under Linux.

 

Hi, I may have found a sollution for WIFI:
Step 1, install the rpmfusion repos, the commands will make sure you have the right repo for your system:

sudo yum localinstall --nogpgcheck http://download1.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm
sudo yum localinstall --nogpgcheck http://download1.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

Then install the driver with the yum package manager but first yum need to update the repos:

yum update

Now the installation:

yum install akmod-wl.x86_64 broadcom-wl.noarch


Hope this helps you guys!

P.S.: Don't forget to reboot ;-)

 

Has anybody already solved the problem of the massively different DPIs of the QHD+ laptop display and a second and maybe third monitor?
I guess most of us will have at least one FullHD or WUXGA display (most likely 24").
The best I could manage so far was to connect one additional display to the Dockingstation via DVI.
The second display which is connected via DisplayPort is not beeing detected.

So now I'm using the 15" QHD+ Laptop display and one 24" FullHD Monitor, this makes for massively different DPI settings. Unfortunately I have not yet found a way
to get X to scale accoring to the various DPI settings. So if it looks ok on the Laptop screen it will be garishly huge on the 24" monitor and it scales OK on the Monitor it will be almost unreadably small on the laptop 15" display.


The only band aid I have found so far is to scale down the monitor display, but that causes the display to be washed out, with the typical look of an LCD running in a non-native resolution:
xrandr --output DP-4 --mode 3200x1800 --pos 0x0 --rotate normal --output DP-0 --scale 1.5x1.5 --mode 1920x1080 --pos 3200x0 --rotate normal

If anybody has a better solution I'd be more then happy to hear about it.

 

Hi,
I've recentlz bought M4800. Everzthong is great but this QHD+ is giving me headache

Thanks
