Introdução

Esta página contém a Errata do Mandriva Linux 2009 Spring (2009.1 ). Isto significa que esta página conterá os problemas conhecidos com o Mandriva Linux 2009 Spring e, onde está disponível, como consertar, previnir ou trabalhar em torno dele. Você também deve ver Notas de Lançamento, que contém mais informações gerais sobre o lançamento do Mandriva Linux 2009 Spring.

Mandriva Linux 2009 Spring está atualmente em desenvolvimento. Durante o ciclo de desenvolvimento, esta página da errata listará os problemas que os usuários encontrarem com os lançamentos beta e Cooker. Enquanto este lançamento estiver em desenvolvimento, os métodos usuais não se aplicam. Atualizações oficiais não serão emitidas para lançamentos beta. Estes problemas serão resolvidos por atualizações diretas da árvore do Cooker, e quando novos lançamentos beta forem feitos, aqueles problemas serão resolvidos então. Problemas ocorridos com lançamentos anteriores ao beta e depois não ocorrerem serão considerados como 'resolvidos'. Onde um problema é válido com um lançamento beta posterior mas não em uma Cooker, este não será considerado 'resolvido', mas uma nota do problema será fixada no Cooker e uma referência para especificar o pacote consertado será incluído na descrição do problema.

Problemas de instalação

Management Users Window

See also Bug #47156

for detailed information and screenshots. When you are installing Mandriva Linux 2009 Spring Alpha 2, do not use Advanced functionality (modifying shel or UID or GID). You would be blocked on this window and then need to restart Mandriva Linux installation.

Keyboard and mouse don't work when you do the graphic card resolution test

See also Bug #46656

for detailed information. When you are installing Mandriva Linux 2009 Spring Alpha 2, the keyboard and mouse don't work when you do the graphic card resolution test. You need to wait that the test is finished.

Problemas de Kernel

Problemas de Hardware

Upgrade of x11-server

As we are now using 1.5.99.3 version waiting for stable release, there are some know issues:

• fglrx is currently not working because of ABI changes. This should be corrected for coming releases
• i810 video card: not working - deactivate DRI to avoid X server crash. A patch has been identified and should be integrated soon
• There are some know bugs with some USB multimedia keyboards. They may have a wrong mapping, then when you hit one of the multimedia key it causes X server crash

SiS 670 / 671-based video adapters do not work

Mandriva Linux 2009 Spring introduces the new X.org server version 1.5. This version of the server requires that all video adapter drivers be based on the libpciaccess system. The external driver used to support some specific SiS adapters, x11-driver-video-sisimedia , has not yet been ported to the libpciaccess system, and so does not work as of Alpha 1. You will need to use the vesa driver to get basic graphics support on these adapters. The author of the driver has expressed an intention to port it to libpciaccess. If this is completed in time, the updated driver will be added to Mandriva Linux 2009 Spring.

Slow or no internet response (particularly web browsing)

IPv6 issues

See also Bug #27070 . There is a known problem with all Linux distributions that enable IPv6 networking (the new standard for network addresses which uses a longer, hexadecimal address format to provide a much larger number of possible addresses. The old standard is IPv4, which gives the four-groups-of-three-digits decimal address format most people are familiar with, e.g. 216.105.167.65). Some systems and networks do not cope well if your system has IPv6 networking enabled. If you experience sluggish response on the Internet - especially when browsing web sites - and cannot find the cause, you should try disabling IPv6. To do this, edit the file /etc/modprobe.conf , add the following line, and reboot:

install ipv6 /bin/true

TCP window scaling

See also Bug #27073 . If this does not resolve the problem, there is another possibility. Most Linux distributions, including Mandriva, enable a kernel feature called TCP window scaling. This is useful for increasing the speed of transfers over very high bandwidth connections. However, a change was made in the default values for TCP window scaling in kernel 2.6.17, which seems to cause very slow network performance for some users with some internet sites. To see if TCP window scaling is the problem, you can disable it with this command:

sysctl -w net.ipv4.tcp_window_scaling=0

If this resolves the problem, you can make the change permanent by adding this line to the file /etc/sysctl.conf

net.ipv4.tcp_window_scaling=0

This will disable TCP window scaling at every boot. If you do use a very high bandwidth network connection - for instance, you regularly transfer large files over a local 100Mbit or 1Gbit network - you may notice that disabling TCP window scaling results in slower performance over this connection. In this case, you could try restoring the pre-2.6.17 default settings rather than disabling TCP window scaling entirely. To do this, add the following line to /etc/sysctl.conf , instead of (not in addition to) the previously suggested one:

net.ipv4.tcp_rmem=4096 87380 174760

This will change the default window scaling settings at every boot.

Problemas de Software

The KDE desktop crash when you launch any application by KDE menu

See also Bug #47068

for detailed information.To solve this problem, update kdebase4-workspace

to kdebase4-workspace-4.1.96-13mdv2009.1

release. 

growisofs and all the tools in dvd+rw-tools package crash when you launch them

See also Bug #47150

and  Bug #47142
for detailed information. To solve this problem, update dvd+rw-tools

to dvd+rw-tools-7.1-1mdv2009.1

release.

K3b the burning tool for CD-ROM and DVD-ROM don't work in burning mode

See also Bug #47173

for detailed information. The workaround for this problem is to use Brasero, this is a 

burning tool for CD-ROM and DVD-ROM available with GNOME Desktop environment. Don't forget to update the dvd+rw-tools

package if you use Brasero (because of the bugs   Bug #47150
and  Bug #47142

)
