Indeed I was also able to set the vgamem to 131072 without my Windows client crashing! That was good but the problem of the resolution to select remains. So I get a list like this:</div><div><br></div><div>2560 x 1440</div><div>2560 x 1600</div><div>2560 x 1600</div><div>2800 x 2100</div><div>3200 x 2400</div><div>3840 x 2160</div><div>4096 x 2160</div><div><br></div><div>but The resolution I want, 5120 x 1440 is not listed and auto resizing the VM only results in more black borders to the screen. So somehow I should inform the Red Hat QXL display controller to add that mode as a possiblity. In my Linux host I could do that by using Xrandr and add the resolution and the refresh rate. But in my Windows Client i do not see that option.</div><div><br></div><div>many thanks for your efforts. I really appreciate it because the actual user feedback for Linux newbee's like myself is rather low.</div><div><br></div><div>kind regards,</div><div><br></div><div><br></div><div><br></div><div><br></div><div>On Tue, 2020-10-06 at 13:46 +0200, Pavel Hrdina wrote:</div><blockquote type="cite" style="margin:0 0 0 .8ex; border-left:2px #729fcf solid;padding-left:1ex"><pre>On Mon, Oct 05, 2020 at 08:28:11PM +0200, <a href="mailto:odoggmts@hotmail.com">odoggmts@hotmail.com</a> wrote:</pre><pre><blockquote type="cite" style="margin:0 0 0 .8ex; border-left:2px #729fcf solid;padding-left:1ex"></blockquote></pre><pre><br></pre><pre>Hi Pavel,</pre><pre>sorry for my late reply.
