<div dir="ltr"><div><div>Hi,<br><br></div>I am working on X.org driver for an arm SoC. It support HDMI video out. The X.org driver + kernel fb driver is working and I get the display. The system uses Ubuntu precise. I have problem while changing the resolution. In our X.org driver we have<br>
<br>pScrn->SwitchMode = fbdevHWSwitchModeWeak();<br><br></div><div>After resolution change operation from 'Displays' applet in ubuntu GDM, I get blank screen. <br><br></div><div>At this stage, if I do ssh and fire 'xrandr' without any argument, the resolution change works fine. I am not able to understand this behavior.<br>
<br><div>If I change resolution from terminal using xrandr, then also I have to use it twice.<br></div><div>e.g. <br>xrandr --output HDMI --mode 1920x1080 --rate 60<br></div><div>xrandr<br></div><div></div><br>
<br></div><div>Please guide me, what I should do in my X.org driver , so resolution change works without need to execute 'xrandr'. <br></div><div></div><br><div>Thanks in advance.<br><br></div><div>Regards,<br>kalpesh<br>
