Thanks Dennis. The information about omapdrm was good, gave something to troubleshoot. On the working (3.4.2-3) kernel, you can do this: # cd /sys/devices/platform/omapdrm.0/drm/card0/card0-HDMI-A-1/ # cat modes 1024x768 800x600 848x480 640x480 On the latest kernel 3.5.2-3 that sysfs path does not exist. :( So I guess the omapdrm driver is not happy. The output of lsmod does not have as much stuff as the 3.4.2-3 kernel had. Here I tried to load omapdrm module: # insmod /lib/modules/3.5.2-3.fc17.armv7hl.omap/kernel/drivers/staging/omapdrm/omapdrm.ko Error: could not insert module /lib/modules/3.5.2-3.fc17.armv7hl.omap/kernel/drivers/staging/omapdrm/omapdrm.ko: Unknown symbol in module On the working kernel, lsmod: # lsmod Module Size Used by lockd 76647 0 sunrpc 229730 1 lockd aes_generic 31238 0 bnep 10592 2 bluetooth 177728 7 bnep arc4 1269 0 nls_ascii 3508 1 vfat 9199 1 fat 48924 1 vfat wl12xx 145546 0 mac80211 442857 1 wl12xx cfg80211 169876 2 mac80211,wl12xx rfkill 16628 5 cfg80211,bluetooth smsc95xx 12138 0 evbug 1926 0 rtc_twl 5447 0 wl12xx_sdio 3387 0 autofs4 22550 2 omapdrm 62957 2 fb_sys_fops 1376 1 omapdrm syscopyarea 3028 1 omapdrm sysfillrect 3304 1 omapdrm sysimgblt 2131 1 omapdrm drm_kms_helper 28433 1 omapdrm drm 201384 2 drm_kms_helper,omapdrm And the unhappy kernel... # lsmod Module Size Used by lockd 76997 0 sunrpc 230092 1 lockd bnep 10600 2 bluetooth 179620 7 bnep rfkill 16628 2 bluetooth nls_ascii 3508 1 vfat 9199 1 fat 49092 1 vfat evbug 1926 0 smsc95xx 12162 0 rtc_twl 5447 0 autofs4 22550 2 As you can see there are some differences. :( -- -Jon _______________________________________________ arm mailing list arm@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/arm
