 Posted: Thu Jul 13, 2017 2:04 pm Post subject: [/solved] Alienware 17 R4 Optimus no screens |
 |
|
System: Alienware 17 R4
Problem: I can't get Optimus to work. When I run startx several things seem to go wrong and XServer shuts down. I have read through relevant chapters at /usr/share/doc/nvidia-drivers-384.47/README.bz2. I have read the gentoo wiki on optimus. I have read through the gentoo wiki on nvidia and the wiki on xorg. I am now reaching out to the community. Maybe someone knows exactly what the issue here is. Below is a list of relevant information about my current configuration.

dustfinger,
You have the teltale signs of Optimus,
nVidia can't see a display, intel and nVidia GPUs but ... a few high end 'gaming laptops' actually have two complete independent graphics setups.
That is, they look like Optimus but are not.
Such laptops allow you to choose GPUs in the BIOS. Do you have that option?
The Intel GPU is active now. If you move the xorg.conf and .xinitrc out of the way, it should just work.
If your system really is non Optimus, choose the nVidia GPU in the BIOS and
Put Xorg.conf
| Code: | Section "Device"
Identifier "nvidia"
Driver "nvidia"
BusID "PCI:1:0:0"
EndSection |
in xorg.conf and again, it should just work.

Hi NeddySeagoon,
I am not with my laptop at the moment, but I found this discussion on the alienware forum:
https://na.alienwarearena.com/ucf/show/1125054/boards/technical-support-1/ForumPost/why-does-my-alienware-17-r4-have-two-graphics-cards
It suggests that the Alienware does have Optimus as well as a Fn + 7 key for toggling between the two GPUs. I will have to take a look when I get home, but I am no sure if that FN + 7 key will work in linux?
| NeddySeagoon wrote: | | a few high end 'gaming laptops' actually have two complete independent graphics setups. |
My system definitely has two GPUs. One is the intel skylake integrated GPU and the other is the nvidia Geforce 1070.
| Code: |
00:02.0 VGA compatible controller: Intel Corporation HD Graphics 530 (rev 06)
01:00.0 VGA compatible controller: NVIDIA Corporation GP104M [GeForce GTX 1070 Mobile] (rev a1)
|
| NeddySeagoon wrote: | | That is, they look like Optimus but are not |
So I don't really have optimus then? I suppose that means that I will have to manually switch between the two GPUs?
| NeddySeagoon wrote: | | If your system really is non Optimus, choose the nVidia GPU in the BIOS |
I looked for such a setting the other day and could not find one, but I will take another look tonight. Perhaps the FN + 7 key will do the same thing?? I will also try out your xorg.conf, but that would definitely turn off any Optimus handling. If my system really does support Optimus then it would be ideal to have it setup to do its thing.
Thank you for taking the time to answer my post!
Cheerio!

Hi NeddySeagoon,
I tried the Xorg.conf that you suggested with only the nvidia device configured. The Xorg.0.log complains that [ 80040.101] (EE) NVIDIA(0): Failed to assign any connected display devices to X screen 0.. I also tried pressing FN + 7 to see if I could force the nvidia GPU to be used and then tried running startx again, but that resulted in the same error.
I had a look in my bios again to see if I can spot a way to change the GPU. I don't see any way in the bios of doing this. From the Main tab it tells me that the Integrated Graphics is Intel Skylake and the Discrete Graphics 1 is Nvidia GFX. There is no option to change the order or anything like that.
I will continue to experiment, but I feel like I am floundering in the dark on this one.

With the following xorg.conf
| Code: |
Section "Module"
Load "modesetting"
EndSection
Section "Device"
Identifier "nvidia"
Driver "nvidia"
BusID "PCI:1:0:0"
Option "DPI" "96 x 96"
Option "AllowEmptyInitialConfig"
Option "Coolbits" "31"
Option "RegistryDwords" "PowerMizerEnable=0x1; PerfLevelSrc=0x2222; PowerMizerDefault=0x1; PowerMizerDefaultAC=0x1"
Option "nvidiaXineramaInfoOverride" "1920x1080+0+0, 1920x1080+1600+0, 1920x1080+0+1080, 1920x1080+1920+1080"
EndSection
|
That configuration may have got me a little closer. In my Xorg.0.log I can now see a lot of activity around modesetting. The output of startx has these two lines:
| Code: |
gdm: failed to open any driver (search paths /usr/lib64/dri)
gdm: Last dlopen error: /usr/lib64/dri/i965_dri.so: cannot open shared object file: No such file or directory
failed to load driver: i965
|
I checked and /usr/lib64/dri/i965_dri.so is a symlink to /usr/lib64/mesa/i965_dri.so which is missing.
At the moment in make.conf I have VIDEO_CARDS="nvidia"
so I changed it to VIDEO_CARDS="nvidia intel 1965"
Before rebuilding @world I wanted to update my kernel so..
From the kernel source tree
| Code: |
$ grep -B 1 'MODULE_FIRMWARE.*SKL' drivers/gpu/drm/i915/intel_guc_loader.c drivers/gpu/drm/i915/intel_csr.c
drivers/gpu/drm/i915/intel_guc_loader.c-#define I915_SKL_GUC_UCODE GUC_FW_PATH(skl, SKL_FW_MAJOR, SKL_FW_MINOR)
drivers/gpu/drm/i915/intel_guc_loader.c:MODULE_FIRMWARE(I915_SKL_GUC_UCODE);
--
drivers/gpu/drm/i915/intel_csr.c-#define I915_CSR_SKL "i915/skl_dmc_ver1_26.bin"
drivers/gpu/drm/i915/intel_csr.c:MODULE_FIRMWARE(I915_CSR_SKL);
|
I added this to the kernel
| Code: |
$ grep -i EXTRA .config
CONFIG_EXTRA_FIRMWARE="i915/skl_dmc_ver1_26.bin"
CONFIG_EXTRA_FIRMWARE_DIR="firmware"
|
Then tried to build the kernel
| Code: |
$ sudo make
Password:
CHK include/config/kernel.release
CHK include/generated/uapi/linux/version.h
CHK include/generated/utsrelease.h
CHK include/generated/bounds.h
CHK include/generated/timeconst.h
CHK include/generated/asm-offsets.h
CALL scripts/checksyscalls.sh
CHK include/generated/compile.h
make[1]: *** No rule to make target 'firmware/i915/skl_dmc_ver1_26.bin', needed by 'firmware/i915/skl_dmc_ver1_26.bin.gen.o'. Stop.
make: *** [Makefile:988: firmware] Error 2
|
So I went to see if the bin was actually there:
| Code: |
$ ls firmware/i915/
skl_dmc_ver1_26.bin.gen.S
|
I was expecting to see skl_dmc_ver1_26.bin. I am not quite sure what to do about the fact that the bin file is just not there. I decided to build @world and will continue experimenting tonight when I am home from work.

I have an optimus laptop and lspci lists the nvidia chip as | Code: | | 01:00.0 3D controller: NVIDIA Corporation GM107M [GeForce GTX 950M] (rev a2) |
So I suspect Neddy may be correct.
EDIT: Initially tried only running on the nvidia chip but it got very hot very fast so I had to spend a week or two getting bumblebee running, I just checked and I still have commented lines in my xorg.conf for running on nvidia. They may work for you | Code: | #Section "ServerLayout"
# Identifier "layout"
# Screen 0 "nvidia"
# Inactive "intel"
#EndSection
#Section "Device"
# Identifier "nvidia"
# Driver "nvidia"
# BusID "PCI:1:0:0"
#EndSection
#Section "Screen"
# Identifier "nvidia"
# Device "nvidia"
# Option "AllowEmptyInitialConfiguration"
#EndSection |

To get it working the key thing was to make sure I had the kernel built against the intel skylake firmware. First I had to configure the kernel to look for i915/skl_dmc_ver1_26.bin in the correct path. By default it simply looks in the firmware path local to the source tree. But sys-kernel/linux-firmware drops the intel skylake firmware in /lib/firmware. I guess this is a well known thing, but it was not known to me.
| Code: |
grep -i firmware /usr/src/linux/.config
CONFIG_PREVENT_FIRMWARE_BUILD=y
CONFIG_FIRMWARE_IN_KERNEL=y
[b]CONFIG_EXTRA_FIRMWARE="i915/skl_dmc_ver1_26.bin"
CONFIG_EXTRA_FIRMWARE_DIR="/lib/firmware"[/b]
# Altera FPGA firmware download module
# CONFIG_DRM_LOAD_EDID_FIRMWARE is not set
# CONFIG_FIRMWARE_EDID is not set
# Firmware Drivers
CONFIG_FIRMWARE_MEMMAP=y
# CONFIG_GOOGLE_FIRMWARE is not set
# EFI (Extensible Firmware Interface) Support
# CONFIG_TEST_FIRMWARE is not set
|
In make.conf I made sure that I had both the intel and nvidia graphics set and the use flag for glamor
| Code: |
VIDEO_CARDS="nvidia intel 1965"
USE="bindist udev nvidia acpi glamor"
|
Then I just used the following xorg config:
| Code: |
Section "Device"
Identifier "nvidia"
Driver "nvidia"
# Change the BusID if necessary. Tips: (lspci | grep -E "VGA|3D") (Change 01:00.0 to 1:0:0)
BusID "PCI:1:00:0"
Option "ConnectedMonitor" "CRT-0"
Option "CustomEDID" "CRT-0:/sys/class/drm/card0-eDP-1/edid"
Option "UseEDID" "true"
# Option "AccelMethod" "none"
EndSection
Section "Device"
Identifier "intel"
Driver "modesetting"
#Driver "intel"
# Change BusID if necessary. Tips: (lspci | grep -E "VGA|3D") (Change 00:02.0 to 0:2:0)
BusID "PCI:0:02:0"
#Option "AccelMethod" "none"
Option "AccelMethod" "sna"
#Option "AccelMethod" "uxa"
# The next three options help to reduce tearing, but reduce performance
Option "TearFree" "True"
Option "Tiling" "True"
Option "SwapbuffersWait" "True"
EndSection
Section "ServerLayout"
Identifier "layout"
Screen 0 "nvidia"
#Screen 1 "nvidia"
Inactive "intel"
#Screen 0 "intel"
#Inactive "nvidia"
EndSection
Section "Monitor"

EndSection
Section "Screen"
Identifier "nvidia"
Device "nvidia"
Option "AllowEmptyInitialConfiguration" "Yes"
EndSection
Section "Screen"
Identifier "intel"
Device "intel"
EndSection
|
Now I have direct rendering
| Code: |
$ glxinfo | grep -iE 'rendering|nvidia'
direct rendering: Yes
server glx vendor string: NVIDIA Corporation
client glx vendor string: NVIDIA Corporation
OpenGL vendor string: NVIDIA Corporation
OpenGL core profile version string: 4.5.0 NVIDIA 384.47
OpenGL core profile shading language version string: 4.50 NVIDIA
GL_NV_parameter_buffer_object2, GL_NV_path_rendering,
GL_NV_path_rendering_shared_edge, GL_NV_pixel_data_range,
GL_NV_shader_thread_shuffle, GL_NV_stereo_view_rendering,
OpenGL version string: 4.5.0 NVIDIA 384.47
OpenGL shading language version string: 4.50 NVIDIA
GL_NV_parameter_buffer_object2, GL_NV_path_rendering,
GL_NV_path_rendering_shared_edge, GL_NV_pixel_data_range,
GL_NV_shader_thread_shuffle, GL_NV_stereo_view_rendering,
OpenGL ES profile version string: OpenGL ES 3.2 NVIDIA 384.47
GL_NV_packed_float_linear, GL_NV_path_rendering,
GL_NV_path_rendering_shared_edge, GL_NV_pixel_buffer_object,
GL_NV_stereo_view_rendering, GL_NV_texture_array, GL_NV_texture_barrier, |
Also, now my firmware library symlink is actually pointing to the mesa library
| Code: |
$ ls -la /usr/lib64/dri/i965_dri.so
lrwxrwxrwx 1 root root 19 May 29 21:07 /usr/lib64/dri/i965_dri.so -> ../mesa/i965_dri.so |
The only issue is now that it seems my nvidia is always on unless I edit my xorg config and make the intel skylake driver always on. That is not really what optimus is all about though. Is there a way to configure xorg to auto switch between the two drivers? If so, then how can I test that this is actually happening?

dustfinger,
A switch between the nVidia and intel graphics requires an Xorg restart at the moment.

Thanks NeddySeagoon,
That will work for me for now. I will try to keep myself in the loop for when support finally comes our way. I have read a bit about the bumblebee project, but I imagine that eventually it will be supported natively by xorg.
