<div dir="ltr">Hi , I am using qemu to experience fodora20 (Fedora-Live-LXDE-i686-20).<br>After I successfully installed fedora , it runs in 1024x768 mode,<br>then I tried to set display resolution to 1680x1050 (or some other 'big' numbers),<br>

No crash happens while display reolution switching.<br><br>If I change '-global qxl-vga.ram_size=67108864 -global qxl-vga.vram_size=9437184 '<br> to '-global qxl-vga.ram_size=67108864 -global qxl-vga.vram_size=67108864 ',<br>
then no crash but 'black screen' I got.<br><br><br>May I get any debug hint ? :)<br><br>Thanks in advance.<br><br><br></div>
