well,I dont think this problem cause by this system.but is also can tell cause by this system.Because in my mine,I think it might got some problem by this system,by only you reinstell system can resolve it.

Hi ,I think your graphic card driver need update

Hi, I try update the driver, but when I updating the driver Nvidia I downloaded from the nvidia page,
I have a error message for the driver and the kernel :S

I install linux mint for example and he showme a non-free Nvidia driver. No is the case in Deepin :S

I Having a possibility of install the driver non free with official repo non free of debian strech???

Very thanks and sorry for my english

Hi,Deepin  15.5 is basing on Debian 8 ,you can driver for debian .

ok, very thanks I try now. I tryed yesterday with ppa for Debian 9 Stretch, but cant installed two or trhee librarys and this crashing the SO

I dont know if the problem now is of kernel of deepin. Not is he same kernel of debian.. I think.

Linux Dell-XPS 4.14.0-deepin2-amd64 #1 SMP PREEMPT Deepin 4.14.12-2 (2018-01-06) x86_64 GNU/Linux -> update only I dont know

And have 4.9 kernell too.

Hi , now deepin can not get driver support from Nvidia company .That is why Nvidia card does not work well with deepin.
Hope this can be solved in next version  

Deepin kernel comes from debian ,and is different .
And its version is internal version ,is mostly different from debian and standard linux .

hooo, ok. I Waiting the next release.

I tryed install the non-free driver nvidia from  the deepin repository, try:

Install nvidia-detect -> recognized of GPU ok
install nvidia-driver -> recomendation from nvidia-detect
install nvidida-setting and nvidia-xconfig

When nvidia-xconfig generate the new /etc/X11/xorg.conf  and restart the pc.
Deeping dont start never again
Display four or five lines in terminal and dont start never.

It very very great distribution of linux, I never tryed other version with, performance interface, and stability of deepin.
Please solve the compatibility with Nvidida non-free drivers pls. Its only the bad of deepin in my opinion

The problem dont is the intel driver????

deepin can work with intel driver .
Problem happens when you have dedicate graphic card or dual graphic card ,which do not provide open-free drivers .

Thanks, but Do you plan to provide support for NVIDIA in the short time?
Regards

They have this plan ,and plan to  make it happen in near several releases .

for this time I conform with the solution in:

https://xn--deepinenespaol-1nb.org/comunidad/controladores/instalar-bumblebee-para-tarjetas-nvidia-optimus-en-deepin/#post-590

after 15 days fighting with the fuck driver of nvidia and bumblebee, I can work, Dont work HDMI or sd lector, but... for this time its ok.

I wait the solution in others futures releases
