Description Jan de Groot 2011-10-17 02:40:38 UTC

commit b1f7f190f9d4f2ab63d3e9ade3e7e04bb4b1f89f introduces a check for a kernel driver bound to the device. This means that vesa refuses to load whenever something kernel-related is loaded for the device.

In case of parallels desktop, there's a kernel driver (prl_tg) that processes size changes of the virtual machine window. This kernel driver is detected by the vesa driver, resulting in "No screens found".

Comment 1 Jeremy Huddleston Sequoia 2011-10-17 11:20:49 UTC

Perhaps we need an update to that API in libpciaccess to return the name of the 
driver to the caller:

int pci_device_get_kernel_driver( struct pci_device * dev, char **name );
