Subject: qemu: Please switch to SDL2

Date: Sat, 29 Jul 2017 00:48:08 +0200

Package: qemu-system-x86
Version: 1:2.8+dfsg-6
Severity: wishlist

Hi!

According to [1], it seems that since version 2.4 in 2015 this project supports
both SDL1.2 and SDL2, and since the recent 2.10 [2] it prefers SDL2 if both are
available.

  [1] http://wiki.qemu.org/ChangeLog/2.4

  [2] http://wiki.qemu.org/ChangeLog/2.10

After more than 5 years of the release of SDL2 and SDL1.2 being under really
minimal support, it would be nice to try to get the most important packages
migrated to SDL2, and this is one of them.

So please consider switching to SDL2 in your next uploads.


Cheers.

I tried switching to SDL2 but it turned out the support was incomplete, like
some functional keys (like resizing the guest display) didn't work in SLD2 but
worked in SDL1.

Now with availability of GTK frontend we'll either switch to that or, better
yet, try to make display modular (a very frequently asked feature is to be
able to install a "headless" qemu without graphics libs), again, with GTK being
the default.

Thanks,

Right, better to have a Qemu using an old version of SDL than a faulty one!

My most sincere thanks for the effort and the quick reply.

Subject: Broken display updating with SDL2

Date: Sat, 14 Oct 2017 09:34:25 +0000

[Message part 1 (text/plain, inline)]

Hi,

I had to apply the attached patch to make the SDL2 UI of any use - the
vanilla version (both Debian Sid package and qemu git master) stops
updating after the window is obscured, minimized, or after a virtual
desktop switch.

It partially reverts the following hack:

Hmm.  Have you tried discussing this upstream?

It looks like you've testcases and good expirence in that area,
sending this stuff to qemu-devel@nongnu.org, with Cc kraxel (who
maintains SDL support in qemu) seems to be a much better idea.

Thank you!
