I seem to be having a weird problem and hope someone can help me out. I got a high resolution monitor to upgrade from my existing one. Here is the output from
Screen 0: minimum 320 x 200, current 3200 x 1080, maximum 8192 x 8192 VGA-0 connected 1280x1024+0+56 (normal left inverted right x axis y axis) 338mm x 270mm 1280x1024 60.0*+ 75.0 1152x864 75.0 1024x768 75.1 70.1 60.0 832x624 74.6 800x600 72.2 75.0 60.3 640x480 75.0 72.8 60.0 720x400 70.1 DVI-0 connected primary 1920x1080+1280+0 (normal left inverted right x axis y axis) 600mm x 340mm 3840x2160 30.0 + 25.0 24.0 30.0 24.0 2560x1440 60.0 1920x1080 60.0* 59.9 30.0 30.0 1600x900 60.0 1280x1024 60.0 1280x800 59.9 1152x864 60.0 1280x720 60.0 59.9 1024x768 60.0 800x600 60.3 720x480 60.0 59.9 640x480 60.0 59.9
One of them (the old one) is connected via VGA, whereas the new one is connected via a dvi to hdmi dongle. I've an integrated GPU
The output from
lspci | grep VGA is
01:05.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] RS880 [Radeon HD 4200]
My question is two fold.
- The Radeon HD 4200 supports resolution only upto 1920x1200 per this thread for dvi. Does this mean that if I get a vga to hdmi dongle, I can get to 2560x1600 resolution? Or do I need to find a new graphics card and insert into an open pci slot?
- I'm also stuck with a bizarre problem. When I suspend/reboot/wake up etc, I need to have my old monitor connected to the VGA port all the time, else the new monitor does not switch on and just stays blank. This has to be configuration/software related. I also followed instructions listed here to pull in some packages, rebooted. But no luck.
I only want to use my new monitor (no dual monitor setup needed). Any pointers much appreciated. Thanks in advance.
