New driver causes enlightenment to resize display to 8x8?

New driver causes enlightenment to resize display to 8x8?

[Marc MERLIN]

After upgrading to xserver-xorg-video-intel 2:2.99.917-1~exp1 , the
performance did improve, but twice, I had e18 crash (its fault, not X's
fault), give me a window that it was going to restart, and when it restarted
the screen went dark.

I went to a text console, and xrandr said this:
Screen 0: minimum 8 x 8, current 8 x 8, maximum 32767 x 32767

xrandr -s anything, including 800x600 said:
xrandr: Configure crtc 0 failed

Restarting X reset things, and I had to delete my enlightenment profile
for it to stop trying to resize to 8x8 on start.

I've used e18 for over a year and I never had this problem until the exact
moment I upgraded the intel driver.
Out of curiosity, even if the bug was with enlightenment, how do I resize
my screen once it's been mistakenly resized to 8x8. Is it a bug that xrandr
was unable to resize it for me?

Thanks,
Marc

xrandr -s is the old XRandR procotol, it should still work but it's not
clear if that is going to be a bug in xrandr misconfiguring CRTC or in
X server/ddx. If you can file a bug and include your Xorg.0.log along
with "xtrace xrandr -s anything" and if you can manage to get an
xf86-video-intel --enable-debug=full log for the above, then I can tell
you where the bug lies.

At any rate "xrandr --output eDP1 --preferred" is what you want.

It works just fine now:
legolas:~$ xrandr -s 2048x1536
legolas:~$ xrandr -s 2880x1620

It just wasn't able to get me out of that 8x8 mode that I got in due to a
bug somewhere (not sure if it's enlightenment or Xorg).

I will try this next time if it happens again.
