Blank Screen on switching from nvidia to intel with ubuntu 16.04 on ASUS TUF FX504

I have recently installed nvidia-415 (415.27) from PPA.
OS: Ubuntu 16.04
System: ASUS TUF FX504 (gaming)
NVIDIA: Geforce 1050 ti
CPU: intel i5 8th gen

following are the observations:-

  • Nvidia mode works fine as I get output on nvidia-smi
  • On switching to Intel mode using NVIDIA-Xserver setting, I get blank screen just after logout and also after reboot.
  • On changing again to Nvidia mode using tty1 in recovery mode using prime-select nvidia everything works fine.

Intel HD Graphics 530 with i915 dirver render latency

I have an desktop with Ubuntu 18.04 installed and only Intel HD Graphics 530 graphics card. It seems that i915 driver installed automatically and works however, it seems that there is lag (latency) in rendering (smth about ~100ms) which is especially noticeable when dragging mouse.

When using windows on the same computer there is no such problem.

How can investigate, where can be problem?

Problem switching GPUs with prime-select (nvidia and intel)

Im pretty new to Linux and Im triying to get working both my integrated Intel and dedicated Nvidia (1050 Ti) GPUs in my dell XPS 9570, with prime-select program, but Im having troubles.

If I dont touch the xorg.conf generated with nvidia-xconfig:

# nvidia-xconfig: X configuration file generated by nvidia-xconfig # nvidia-xconfig:  version 430.50   Section "ServerLayout"     Identifier     "Layout0"     Screen      0  "Screen0" 0 0     InputDevice    "Keyboard0" "CoreKeyboard"     InputDevice    "Mouse0" "CorePointer" EndSection  Section "Files" EndSection  Section "InputDevice"      # generated from default     Identifier     "Mouse0"     Driver         "mouse"     Option         "Protocol" "auto"     Option         "Device" "/dev/psaux"     Option         "Emulate3Buttons" "no"     Option         "ZAxisMapping" "4 5" EndSection  Section "InputDevice"      # generated from default     Identifier     "Keyboard0"     Driver         "kbd" EndSection  Section "Monitor"     Identifier     "Monitor0"     VendorName     "Unknown"     ModelName      "Unknown"     Option         "DPMS" EndSection  Section "Device"     Identifier     "Device0"     Driver         "nvidia"     VendorName     "NVIDIA Corporation" EndSection  Section "Screen"     Identifier     "Screen0"     Device         "Device0"     Monitor        "Monitor0"     DefaultDepth    24     SubSection     "Display"         Depth       24     EndSubSection EndSection 

my intel graphic works great but a I get a black screen with the nvidia one.

If i use this xorg.conf (I took it in nvidia forum):

Section "ServerLayout"     Identifier     "Layout0"     Screen      0  "nvidia"     Inactive       "intel" EndSection  Section "Device"     Identifier     "intel"     Driver     "modesetting"     BusID      "PCI:0@0:2:0"     Option     "AccelMethod" "None" EndSection  Section "Screen"     Identifier     "intel"     Device     "intel" EndSection  Section "Device"     Identifier     "nvidia"     BusID      "PCI:1@0:0:0"     Driver         "nvidia"     VendorName     "NVIDIA Corporation"     Option     "ConstrainCursor" "off" EndSection  Section "Screen"     Identifier     "nvidia"     Device         "nvidia"     Option     "AllowEmptyInitialConfiguration" "on"     Option     "IgnoreDisplayDevices" "CRT" EndSection 

the nvidia gpu works but the intel one get black screen in booting.

Any ideas to fix this? I purge and reinstal nvidia (as usual pipeline) many times, but the error keeps.

Thank you.

Configure Ubuntu 18.04.3 with Intel AX200

I recently received a new ThinkPad P1 Gen 2 Laptop with an Intel AX200 Network Adapter and installed Ubuntu 18.04.3 LTS. Ubuntu didn’t recognize the adapter right off the bat (“No Wi-Fi Adapter Found”), so I searched around and saw the AX200 is supported starting in Linux 5.1, meaning my version falls short:

$ uname -rs Linux 5.0.0-23-generic

I read thru a bunch of posts surrounding similar problems which all pointed towards backport as a solution, so I followed the instructions on the bottom of this page in the “How to install the driver” section (and reproduced in this post). I had no problems with the install, but nothing has changed after rebooting: still no wireless adapter found.

I’m out of ideas at the moment. Does anyone see what I’ve done wrong or have ideas for other solutions?

Librería sympy: Tengo el error Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll

Verdaderamente ya estoy frustrado y no le encuentro solución, vean que estoy tratando de usar la libreria sympy de Python, pero al tratar de escribir código para que este me devuelva la gráfica de una función me devuelve el siguiente error: Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll.

Lo que estoy haciendo es lo siguiente:

from sympy import * x,y,z = symbols("x y z") print(plot(cos(x))) 

Luego de hacer ese codigo tan sencillo para mostrar la gráfica de cos(x) obtengo en la salida el siguiente error:

INTEL MKL ERROR: %1 no es una aplicaci¾n Win32 vßlida. mkl_intel_thread.dll. Intel MKL FATAL ERROR: Cannot load mkl_intel_thread.dll. 

Anexo también que este error se presenta solo a la hora de gráficar, todo lo demás funciona correctamente. Lo único que se me ocurre hasta ahora es que el error sea debido al procesador ya que mi procesador es AMD y el dll que intenta ejecutar mi editor de código hace referencia a nucleos de un procesador intel.

Ubuntu/Linux Mint/Fedora/Manjaro laptop screen flickering with intel graphics

I installed Linux Mint (17 more or less) on a Dell Inspiron 15 Series 7000 i7 Skylake and it worked beautifully for a while. After some OS update (before LM 18) a flicker started to show up.

I read this is a common problem. I’ve tried several workarounds:

  • I’ve been playing with the 20-intel.conf file
  • I’ve added the i915.enable_rc6=0 option to grub on startup
  • I’ve removed the xserver-xorg-video-intel

None of them seems to work. The only option that really works has been to disable the graphic card (entering into LM rendering mode, or through an option in the 20-intel.conf file), but the laptop gets too warm.

And as the title suggests, I’ve tried other distros, even not related to Ubuntu, as Fedora and Manjaro. All of them (including Ubuntu) have shown the same misbehavior.

In my laptop I also have LM Xfce 17.3 in one partition. It’s running the 4.4.0-148-generic kernel, and it does not show such misbehaviour. It makes me think that the problem is not the hardware, but the drivers.

In this image (LM 19.2, 4.15.0-62-generic kernel) you’ll see what I’m talking about. The laptop is unusable under these circumstances.

Any more ideas are appreciated. Thank you in advanced!!

PC with Optane + Intel RST, Will Not Boot Into Ubuntu

I have an identical problem to the one posted here:

Can't boot Ubuntu because Windows 10 rewrites entire EFI partition [Solved]

In short, I have managed to install ubuntu 18.04 alongside windows 10 on an HP Pavilion that has Intel Optane & Intel Rapid Storage Tech (Which uses RAID). At first the ubuntu installation wizard couldn’t identify the windows partition, but after I entered the command “sudo dmraid -E -r /dev/sda” in a live usb trial session it suddenly worked.

Now the Ubuntu is installed but the PC will not boot into it. Boot options (F9) do not recognize any other OS than Windos. I have tried all the options listed in the above post to no avail.

The “solution” given in the post was to disable the Intel Optane, but I paid good money for it and I would certainly like it to continue working on the Windows partition.

Has anyone encountered this problem and managed to boot into Ubuntu without disabling Optane from the Windows partition?

Thanks in advance! Steve
