Created attachment 362338 [details] The xorg log file I just changed the graphics card from ATI 9800XT to Geforce 6800Ultra for my PowerMac G5 running gentoo ppc64, and reinstalled the system from the newest stage3 package on genoo official website. Everything went well for emerging ebuilds, till I ran startx. I got the first screen with rectangles and froze, and X died after while. I use nouveau graphics driver version 1.0.9, and xorg-server-1.14.3-r2. The Xorg log file is attached. Here is the emerge info: Portage 2.2.1 (default/linux/powerpc/ppc64/13.0/64bit-userland, gcc-4.7.3, glibc-2.15-r3, 3.10.7-gentoo-r1 ppc64) ================================================================= System uname: Linux-3.10.7-gentoo-r1-ppc64-PPC970,_altivec_supported-with-gentoo-2.2 KiB Mem: 3491588 total, 3140144 free KiB Swap: 1534200 total, 1534200 free Timestamp of tree: Tue, 29 Oct 2013 15:30:01 +0000 ld GNU ld (GNU Binutils) 2.23.1 app-shells/bash: 4.2_p45 dev-lang/python: 2.7.5-r3, 3.2.5-r3 dev-util/cmake: 2.8.10.2-r2 dev-util/pkgconfig: 0.28 sys-apps/baselayout: 2.2 sys-apps/openrc: 0.11.8 sys-apps/sandbox: 2.6-r1 sys-devel/autoconf: 2.13, 2.69 sys-devel/automake: 1.11.6, 1.13.4 sys-devel/binutils: 2.23.1 sys-devel/gcc: 4.7.3-r1 sys-devel/gcc-config: 1.7.3 sys-devel/libtool: 2.4.2 sys-devel/make: 3.82-r4 sys-kernel/linux-headers: 3.9 (virtual/os-headers) sys-libs/glibc: 2.15-r3 Repositories: gentoo x-portage ACCEPT_KEYWORDS="ppc64" ACCEPT_LICENSE="* -@EULA" CBUILD="powerpc64-unknown-linux-gnu" CFLAGS="-O2 -mcpu=970 -mtune=970 -maltivec -mabi=altivec -mpowerpc64 -fno-strict-aliasing -fomit-frame-pointer -pipe" CHOST="powerpc64-unknown-linux-gnu" CONFIG_PROTECT="/etc /usr/share/gnupg/qualified.txt" CONFIG_PROTECT_MASK="/etc/ca-certificates.conf /etc/dconf /etc/env.d /etc/fonts/fonts.conf /etc/gconf /etc/gentoo-release /etc/revdep-rebuild /etc/sandbox.d /etc/terminfo" CXXFLAGS="-O2 -mcpu=970 -mtune=970 -maltivec -mabi=altivec -mpowerpc64 -fno-strict-aliasing -fomit-frame-pointer -pipe" DISTDIR="/usr/portage/distfiles" FCFLAGS="-O2 -pipe" FEATURES="assume-digests binpkg-logs config-protect-if-modified distlocks ebuild-locks fixlafiles merge-sync news parallel-fetch preserve-libs protect-owned sandbox sfperms strict unknown-features-warn unmerge-logs unmerge-orphans userfetch userpriv usersandbox usersync" FFLAGS="-O2 -pipe" GENTOO_MIRRORS="ftp://ftp.lecl.net/pub/gentoo/ ftp://212.219.56.132/sites/www.ibiblio.org/gentoo/ ftp://ftp.free.fr/mirrors/ftp.gentoo.org/ ftp://212.219.56.133/sites/www.ibiblio.org/gentoo/" LANG="en_US.UTF-8" LDFLAGS="-Wl,-O1 -Wl,--as-needed" MAKEOPTS="-j9" PKGDIR="/usr/portage/packages" PORTAGE_CONFIGROOT="/" PORTAGE_RSYNC_OPTS="--recursive --links --safe-links --perms --times --omit-dir-times --compress --force --whole-file --delete --stats --human-readable --timeout=180 --exclude=/distfiles --exclude=/local --exclude=/packages" PORTAGE_TMPDIR="/var/tmp" PORTDIR="/usr/portage" PORTDIR_OVERLAY="/usr/local/portage" SYNC="rsync://rsync.gentoo.org/gentoo-portage" USE="X acl altivec berkdb bzip2 cjk cli cracklib crypt cxx dbus dri fortran gdbm gnome gtk ibm iconv ipv6 modules mudflap ncurses nls nptl nptlonly openmp pam pcre ppc64 readline session ssl tcpd unicode zlib" ALSA_CARDS="aoa" APACHE2_MODULES="authn_core authz_core socache_shmcb unixd actions alias auth_basic authn_alias authn_anon authn_dbm authn_default authn_file authz_dbm authz_default authz_groupfile authz_host authz_owner authz_user autoindex cache cgi cgid dav dav_fs dav_lock deflate dir disk_cache env expires ext_filter file_cache filter headers include info log_config logio mem_cache mime mime_magic negotiation rewrite setenvif speling status unique_id userdir usertrack vhost_alias" CALLIGRA_FEATURES="kexi words flow plan sheets stage tables krita karbon braindump author" CAMERAS="ptp2" COLLECTD_PLUGINS="df interface irq load memory rrdtool swap syslog" ELIBC="glibc" GPSD_PROTOCOLS="ashtech aivdm earthmate evermore fv18 garmin garmintxt gpsclock itrax mtk3301 nmea ntrip navcom oceanserver oldstyle oncore rtcm104v2 rtcm104v3 sirf superstar2 timing tsip tripmate tnt ubx" INPUT_DEVICES="evdev keyboard mouse" KERNEL="linux" LCD_DEVICES="bayrad cfontz cfontz633 glk hd44780 lb216 lcdm001 mtxorb ncurses text" LIBREOFFICE_EXTENSIONS="presenter-console presenter-minimizer" LINGUAS="en_US zh_CN" OFFICE_IMPLEMENTATION="libreoffice" PHP_TARGETS="php5-5" PYTHON_SINGLE_TARGET="python2_7" PYTHON_TARGETS="python2_7 python3_2" RUBY_TARGETS="ruby19 ruby18" USERLAND="GNU" VIDEO_CARDS="nouveau" XTABLES_ADDONS="quota2 psd pknock lscan length2 ipv4options ipset ipp2p iface geoip fuzzy condition tee tarpit sysrq steal rawnat logmark ipmark dhcpmac delude chaos account" Unset: CPPFLAGS, CTARGET, EMERGE_DEFAULT_OPTS, INSTALL_MASK, LC_ALL, PORTAGE_BUNZIP2_COMMAND, PORTAGE_COMPRESS, PORTAGE_COMPRESS_FLAGS, PORTAGE_RSYNC_EXTRA_OPTS, USE_PYTHON
This problem concerns with nouveau's acceleration function. I tried to disable it by putting "NoAccel" in xorg.conf, X worked so was also gnome.
我装了x11-base/xorg-server-1.14.3-r2 with x11-drivers/xf86-video-nouveau-1.0.9之后,打开Emacs滚动白屏,xterm打开也白屏,然后非得将.Xresources注释掉字体颜色什么的,用默认的配置才能操作,不然我都看不到文字。然后我尝试回滚xorg-server,然后竟然work了--
I updated my system, now with: kernel 3.12.1 mesa 9.2.3 nouveau 1.0.10 xorg-server 1.14.4 After I put option '"ShadowBF" "True"' in xorg.conf, the nouveau driver works with acceleration. In glxinfo it has "direct rendering: Yes", and no nouveau error in dmesg and Xorg.0.log.
Actually this is not HW acceleration by using ShadowFB. In Xorg.0.log there is "Using Shadow Framebuffer - acceleration disabled", so I still have a broken nouveau driver with acceleration. When using ShadowFB it seems the graphics operations are faster than that NoAccel option is enabled on my system. The 3D seems not supported, there is no difference in FPS running glxgears in both situations.
Is this still a problem? Reopen if it is.
