The display= has a HD resolution of 1920 x 1080 pixel, which seems to make VESA unusable. I ha= d to use x86-video-scfb - which is a pain in the ass: extremely slow, keystrokes som= etimes pass through from the console to the graphics screen (it looks like this, I have= no better desription for that phenomenon). Under load, X11 is unusable since the CPU = has to render the whole screen alone. A similar situation arose with Lenovo ThinkPad X240 with high resolution sc= reens and Haswell/HD4600 iGPU. I'm not familiar with the VESA driver. I left that path due to its resoluti= on limitations. We deal with modern hardware and I'm not willing to purchase o= utdated hardware for the sake of the OS. On most laptops with Haswell CPUs we migra= ted to Linux - with great success. As a sideeffect things run more smooth right now. Len= ovo offers a new type of WiFi NIC which also isn't supported by FreeBSD. The problem wit= h Lenovo is that their UEFI doesn't allow to simply swap the miniPCIe WiFi NIC for a su= pported device. With most recent and modern products from Lenovo and FreeBSD (even = CURRENT) we ended up dead in the water.=20 In general there is a serious problem with the graphics support in FreeBSD.= Recent hardware from AMD and Intel isn't supported, only nVidia offers support via= their BLOB. FreeBSD dropped also the nouveau driver.=20 oh =20 --Sig_/lEUrF8X+oQslPtItLcxYzgG Content-Type: application/pgp-signature Content-Description: OpenPGP digital signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJUpGEkAAoJEOgBcD7A/5N8tMsIAL/sNGPS1SwREgW+DrqhJOwF 2JTE2Sv+TP8WN/8wjCWj4hsneRUX6TjBPbT2cmcNy/wfRsRjRgvmMnzE6ZjerwaU KI8Z1yykkKM+1uWRBbDtXUQc5DaNvGZWIV8xQPCOPSAzWQOHpNfhPNb+5nTk7h57 czjaqd3KuAncFChvdwNddGD9tnYE6QJwaMwTeRn0vEU6AzGlM5Ppc471tjVvfuJx ideG62TrU6LvJOTuJrOQbIj2lYN03UirlJBvlm3xkfZz3/ORnx98PzCmtTQlWJV0 VmJsqwrrYtYEELGkmfuUJId3MRxZFaZkLI75yahPVdE3NyCpgyhggU3vdONGORo= =5+6+ -----END PGP SIGNATURE----- --Sig_/lEUrF8X+oQslPtItLcxYzgG--
