I have an NVidia graphics card in my Fedora 18 system and I’ve been using the NVidia drivers but found that the print screen and alt+print screen produced badly corrupted or all black screen shots.
Seeing as the problem has persisted through multiple upgrades of the nvidia modules on my workstation I guess that Nvidia is unwilling or unable to fix the problem under Linux.
So to remove the NVidia rpms (from rpmforge):
# change to a virtual terminal # CTRL + ALT + F2 # login as root su - or do sudo... su - # remove the packages rpm -qa | grep -i nvidia | xargs yum remove # for some reason this failed and said # to continue use yum load-transaction # the /tmp/yum*** file so I did. # replace the X's with the actual filename yum load-transaction /tmp/yumXXXXXXXXXXXXXXXXXXXXXXX # reboot shutdown -r now # on reboot you should now be running # nouveau [root@bb01 ~]# lsmod | grep nouveau nouveau 941736 2 mxm_wmi 12865 1 nouveau i2c_algo_bit 13257 1 nouveau ttm 79629 1 nouveau drm_kms_helper 46708 1 nouveau drm 264680 4 ttm,drm_kms_helper,nouveau i2c_core 38353 5 drm,i2c_i801,drm_kms_helper,i2c_algo_bit,nouveau wmi 18697 3 mxm_wmi,nouveau,asus_wmi video 18991 2 nouveau,asus_wmi
There may be a slight reduction in video quality / performance with the opensource driver (IMO) but the return of functional screenshots makes up for it.
