@Nexarian big thanks for your very hard work on on-the-fly resizing.

We're in the freeze phase. I'm performing further tests before the release.

#1860 and #1864 are left before v0.9.16.

Maybe we should create a separate section in the release note for on-the-fly resizing. It is a significant change.

I've uploaded a YouTube video how on-the-fly resizing works. It would be useful to put a link in the release note. https://youtu.be/6kfAkyLUgFY

@Nexarian I've raised a new issue #1867 related to on-the-fly resizing. I think the priority is not very high but we should address the issue someday.

I've just updated [[https://github.com/neutrinolabs/xrdp/wiki/NEWS]] after all the updates this weekend. I think it's got everything in, including the link above so it can form the basis of the release notes. I'd appreciate it if you could check I haven't left anything out.

@metalefty

Thanks a lot.

@metalefty

@Nexarian I raise another issue #1869. I haven't performed a detailed investigation but this might be a regression of on-the-fly resizing. We should fix it after the release.

@matt335672 We need to mention the issue as known issues in the release note. Can you also test if #1869 reproduces?

matt335672

@matt335672

neutrinolabs/xrdp#1869 updated.

Nexarian

@Nexarian

I also commented on the issue. In short, I don't think this issue is related to the dynamic resize change. I think it's been around in XRDP for some time.

Nexarian

@Nexarian

The problem was I could never get a consistent way to reproduce it. It felt non-determistic.

Nexarian

@Nexarian

Does this community have any connections to those who work on the Microsoft Clients so we could inform them more directly of the bug discovered in neutrinolabs/xrdp#1869

metalefty

@metalefty

@matt335672 I'm thinking that including a security fix in 0.9.16 release, reported to xrdp-core mailing list. It shouldn't be a problem in the most use case of xrdp. So I'll raise the fix as a usual PR.

matt335672

@matt335672

OK - sounds good.

metalefty

@metalefty

Merged #1872. Everything is done for 0.9.16. Thank you @Nexarian @aquesnel for your great work. I'll release after README.md and NEWS.md. The release will be Apr 30 or May 1.

BTW, the gitter mobile app sucks on threaded replies :(

Nexarian

@Nexarian

I didn't even know that existed lol

metalefty

@metalefty

Accessing via mobile browser works well. The app is not very worth. Uninstalled.

@aquesnel

I might be able to get more traction using the Windows client and debugging with WinDBG

@Nexarian i didn't know you can debug Microsoft tools, how do you set that up?

@AdrianodaSilva2017

Hello guys.
Please, would anyone know how to indicate an elegant solution to that problem of Ubuntu 20.04, which opens a prompt window asking for authentication at all times by XRDP?

For example, after authenticating on the computer, when accessing the desktop, a "prompt" message appears saying that authentication is required to create a color profile. And then he waits for the password to be entered.

And it always repeats, randomly, the same message.

I saw a solution on the internet, in which the person suggests creating a script to generically disable this "prompt" in linux. This solution did not seem very correct to me, considering that some situations the operating system really needs a confirmation by typing the password.

What is the correct way to resolve this?

@AdrianodaSilva2017

Ok. So, please, can someone tell me what the distribution is with a standard installation for use in a corporate office, that it is recommended to install XRDP with XORGXRDP without having any problems or discomfort for the user? And would you know what would be the standard method for installing XRDP in this case?

I've made massive progress on getting egfx working with dynamic resize and the Microsoft clients!

@matt335672

Anyone got an idea where these numbers come from in sesman/chansrv/clipboard_common.h

#define CB_FORMAT_HTML                  0xD010
#define CB_FORMAT_PNG                   0xD011
#define CB_FORMAT_JPEG                  0xD012
#define CB_FORMAT_GIF                   0xD013
#define CB_FORMAT_FILE                  0xC0BC

They appear to be hard-coded defines for Registered Clipboard Formats but I'm unable to reverse-map them to meaningful textual names. It might be my lack of knowledge of power shell.

I'm only really bothered about CB_FORMAT_FILE as we're using it, and I'm trying to restructure these defines as part of fixing neutrinolabs/xrdp#1885

Will anyone get a chance to look at this fix anytime soon: neutrinolabs/xorgxrdp#193 ?

@Nexarian

Not specifically an XRDP issue/bug, but don't ever set the umask of your system to 027 -- XRDP WILL NOT install!

And then you'll have to delete a lot of directories to figure out how to get it to work again...

metalefty

@metalefty

what's up?

Nexarian

@Nexarian

Nothing's up, just ran into this helping a colleague get it installed.

matt335672

@matt335672

Just fixed the CI stuff (neutrinolabs/xrdp#1902). Please rebase on latest devel where possible.

Apologies for not doing this sooner. I'd just hoped it was a transient thing that would go away. When no-one else had reported the same thing though, it was clearly a problem on our side.

Good news. Oracle provides ARM 4 core and 24 GB RAM as Always Free instances. https://www.oracle.com/news/announcement/oracle-unlocks-power-of-arm-processors-at-one-cent-per-core-hour-2021-05-25/

Nexarian

@Nexarian

@matt335672 @aquesnel I've updated neutrinolabs/xrdp#1895, addressed all your comments, rebased from devel (and squashed), and then tested to make sure it still works!

Nexarian

@Nexarian

The other thing I've realized is that this will need to be merged with the changes for neutrinolabs/xrdp#1612 at some point as well.

I think this refactor helps centralize the monitor processing logic, but there is more to do in order to get HiDpi working.

metalefty

@metalefty

Hi there, I've enabled the discussions feature of GitHub. It must be very helpful to discuss and share ideas for new features or refactoring.

#1910 is the first post. It turned out why audio redirection is not working on the recent Linux distro. PulseAudio is not started as a child process of xrdp-sesman.

@Nexarian

I can't seem to get Gnome to work at all with the newest Ubuntu Kernel. At least, not with Nvidia enabled. Always black screen.

matt335672

@matt335672

@Nexarian - Is that on the console, xrdp, or both?

I don't have an NVidia hardware but I can try the kernel on a VM easily. What's the kernel version?

On a separate note about brokenness, I'm not able to access github web pages at the moment from Firefox. I'm getting this error:-

mate is gnome right?

There was a recent issue in -questions with Ubuntu not working until that DBUS env was unset even though it was unset in startwm.sh

matt335672

@matt335672

Mate is GNOME 2 based, at least according to https://mate-desktop.org/. I don't think it makes the same assumptions about the DBUS implementation that GNOME 3 makes. Earlier GNOME 3 releases (like the one in RHEL 7) seemed a bit saner to me.
