#StackBounty: #windows-10 #drivers #miracast Miracast no longer working on Windows 10 laptop

Bounty: 50

I have a Dell Inspiron 17 5748 running Windows 10 1709 (Fall Creators Update). A good year ago I was able to wirelessly duplicate my laptop’s screen to a Samsung UE40J6200 TV. I remember having to install an Intel wireless card and the need to install a piece of software called Intel WiDi to make it work.

I didn’t use the functionality for a while and have reinstalled Windows 10 on that laptop since. I looked for the WiDi drivers and found that Intel has discontinued the product saying that Windows now has good Miracast support that can be used instead. The additional bonus would be that an Intel wireless card is no longer required.

Unfortunately I haven’t been able to use it with this laptop since then. Whenever I put my TV in the “screen mirroring” mode, the laptop is able to see the TV when choosing the function to connect to a wireless display. The laptop seems to be able to connect and usually the TV will show the laptop’s display for about 5 seconds before the image either freezes or the connection is dropped.

What I have tried so far:

  • Updated wireless card drivers to latest version
  • Updated graphics card drivers to the latest version on the Dell website
  • Updated graphics card drivers to the latest version from Intel (using a manual installation option because apparently Dell blocks the installation of the generic Intel drivers now)
  • Tried a different Windows 10 machine (a Cherrytrail tablet with a Realtek wireless card. This works fine although the tablet doesn’t have the latest Windows updates)
  • Tried a Windows 10 Mobile device. This works fine.
  • Verified that the driver and hardware supports a wireless display using dxdiag (using these instructions: How to check if your PC supports Miracast
  • Verified that the system supports a wireless display using an alternate method (netsh wlan sho d command in a command prompt)
  • Connected laptop and TV to my 2.4GHz wireless network instead of having the laptop on the 5GHz network and the TV connected with a wire (this shouldn’t matter as Miracast uses WiFi Direct)

I’m now at my wits end as to what I can try next. Google tells me many people complain about Miracast being broken after certain Windows 10 updates but there is never a definite solution available.

The relevant hardware:

  • Core i5 5200U with Intel HD Graphics 5500
  • Intel AC7265 wireless card
  • Samsung UE40J6200 TV
  • Wireless network running on my provider’s router (5GHz 802.11AC with a 40MHz wide channel on free channels, 2.4GHz 802.11N with a 20MHz channel and having interference from neighbor’s access points)

#StackBounty: #x11 #drivers #x-server #skylake Software rendering mode after Linux Mint update

Bounty: 50

After I did some security updates, my video display became unstable (it was showing dust when some animations were to be displayed, as if the vidao cable was incorrectly plugged), I did not really know what to do so I uninstalled the latest package installed by the security update which was named “xserver-xorg-core-lts-vivid”. Then xserver stopped working…I followed some tutorial, installed some packages (as far as I remember “xserver-xorg-video-intel” and “cinnamon”) and then, I could get my GUI/desktop back).

However, now the system complains that it runs in “software rendering mode” and it’s true the computer became slower, specially when rendering graphics.

So I believe there is a problem with my driver…?

I see /var/log/Xorg.0.log reports:

[     4.680] (EE) AIGLX error: Calling driver entry point failed
[     4.680] (EE) AIGLX: reverting to software rendering

Here is the information I can supply right now:

The “Gestionnaire de pilote” (probably “Driver manager” in English) is empty.

Could there be a driver mismatch (sudo lshw -C video reports i1915, glxinfo reports i965).

What operation could help xserver use my video card correctly?

#StackBounty: #windows-7 #laptop #audio #drivers #volume-mixer Why don't device and app sound mixers match?

Bounty: 50

My question is specified in the title, to be more exact I would like to show this particular screenshot of the sound mixer:

sound mixer mismatch

As you can see here, the volume of the IE reached the maximum level, but the device volume barely exceed the middle.

There are more crucial problems here – even if I set all settings to max, many games or movies are really quiet, and in accordance with the mixer, they don’t use whole volume of the device.

Why is it happening? Is there any other explanations except outdated drivers (my laptop is somewhat outdated, so there are a number of modern drivers not officially supported by the laptop)?

Technical details: laptop HP Pavillion dv7 6053er. I don’t know the exact model of my sound card, but my Device Manager says “IDT High Definition Audio Codec” + “Audio Intel(R) for Displays” and meanwhile I have beats audio logo on the bottom of the laptop.

EDIT.

To be more precise, I can toggle mixer to any level of any app without any problem, but i don’t understand why max possible volume of an app doesn’t indicate max volume in the device mixer. The master volume never reaches 100%, and if i change it, the app volume changes respectively

EDIT v2.
If it helps – i found that this problem doesn’t happen when a headset is plugged. Also here some other screenshots with other programs that tell that this problem is system-wide:
