Agora o problema que tive foi num Servidor Windows 2003, em produção numa academia cliente nosso. O servidor apresentava vários erros ao ser iniciado, todos relacionados ao spooler com Event ID 7031 e 7034, inclusive erros cabulosos de memória que bloqueavam o início do serviço de terminais (Terminal Service / RDP), ou seja caos geral no cliente que nem conseguia usar seu sistema.

Neste caso eu não podia simplesmente apagar a pasta do spooler, conforme mencionado nos últimos 2 artigos da saga, pois teria que reconfigurar várias impressoras em várias estações de trabalho, tudo do zero, sendo que nem fui eu que fiz as configurações originais. Então fui pesquisando mais a fundo e fuçando nos registros do Windows, depois de fazer um backup da máquina virtual, claro.

Encontrei a dica no blog do Renato, para remover impressora por impressora nos registros do Windows para identificar qual é a causadora do problema, em HKEY_LOCAL_MACHINE \SYSTEM\ CurrentControlSet\Control\Print\Printers. Depois de remover cada impressora eu tentava iniciar o serviço do Spooler novamente, mas ao entrar na lista de Impressoras e aparelhos de fax o serviço era derrubado novamente. Mas bem perto desta dica resolvi fazer o mesmo na chave Monitors, e encontrei o culpado, o driver de porta TCP/IP da HP (hptcpmon.dll). Bastou remover a chave para que spooler voltasse a funcionar com sua lista completa de impressoras.

Algumas impressoras realmente usavam este driver TCP/IP da HP, então ao entrar nas configurações e em Porta não havia nenhuma porta conectada. Bastou adicionar a Standard TCP/IP Port (driver padrão do Windows)  com o respectivo IP da impressora para que estas voltassem a funcionar sem usar o driver da HP. Vualá!

Dica: Evite ao máximo instalar drivers de terceiros! É a coisa que mais gera problemas e instabilidades no Windows. Use drivers simples, apenas o driver, evitando grandes instaladores e softwares utilitários com seus updates, principalmente em servidores. De preferência para drivers Universais.

GApps: Use the recomended package for Android 4.2.2 / CM 10.1 Modem CwM flash updates for CM9/CM10/CM10.1 MTD ROMs, by cdesai. You can also just copy modem.bin to /radio. PDroid Privacy Protection CwM Patch for CM10.1 Android 4.2.2.

• Works on latest CM10.1 official, @cdesai, @humberos and @alroger builds.
• The app to be used is PDroidManager now. It can be found in the Market but it is already inclued in the Install ZIP.

NoMoarPowah! Galaxy Tab stockblue theme based on ironheart’s theme.

• CwM install package

Kernels

• Kernels for p1 and p1ln included in the same automated ZIP. CDMA has it’s own ZIP.
• Use boot.img, boot_p1ln.img inside the ROM ZIP if you want to try other CM10.1 builds, like the CyanogenMod official and AOKP. Android 4.2.2! Kernel 3.0!
• Flash with heimdall like this:
  • Press Power + VolDown untill you get the Download screen or PC <–> Tab screen.
  • heimdall flash –kernel boot.img –recovery boot.img
• Or just replace boot.img inside the ROM ZIP with your desired kernel.

heimdall flash --kernel boot.img --recovery boot.img

ATENTION: I assume you are following the CM10.1 conversations in the XDA threads. Make sure you have the required flashing background / skills. In sum, if not already in CM10 / CM10.1:

• Must be on Gingerbread or newer with unlocked bootloaders.
• Must have CwM Recovery.

The Overcome guide is a good start before anything. Easy restock from Gingerbread, in case you get any strange simptoms.

• Flash full stock Gingerbread (with repartition) via ODIN.
• Flash the Kernel included in the CM10.1 ZIP for your model (boot_p1n.img for P1000N for example), using the heimdall command above.
• Boot directly into CwM Recovery, holding Power + VolUp.
• Flash CM10.1 ROM, if it reboots by itself repeat the step above.
• If you want PDroid, flash PDroid Patches.
• If you want Google’s stuff, flash latest GApps for Android 4.2.2.
• Only Reboot after everything.

Troubleshooting

• Mobile, Data, 3G problems? This ROM comes with the JPZ modem. You might need to flash your customary modem back. Just copy your modem.bin to /radio in the Tab.
• Wrong MAC? Wrong IMEI? Try restoring files from /sdcard/backup/efs*/* to /efs/. If you don’t have a backup, then start over with FULL Restock, and next time save your backup/efs folders, which are created everytime you install CM10.1.
• Market problems? Clear Google Services Framework data and reboot.
• Multiple users is NOT supported by the OpenPDroid Patches.
• Developer options: can’t find it? It’s hidden! Tap About tablet / Build number 7 times to unlock it.
• No touch? That means you got the wrong kernel installed. A couple of builds had problems identifying the exact model. Just flash your kernel through recovery or heimdall / odin.
• No boot? Stuck at the SAMSUNG logo? Flash the correct kernel using Download Mode using heimdall!

Finalmente!

A Valve finalmente está investindo no Linux, e até admitiu que pode fazer seus jogos rodarem mais rápido no Linux do que qualquer outro OS. Fico feliz em ver que estão trabalhando de perto com a nVidia e até ajudaram a melhorar a performance de seus últimos drivers proprietários.

Depois de um tempo que me inscrevi recebi minha autorização para participar do Beta. Acabei de rodar o Team Fortress 2 Beta, que está livre para testes no Steam. Mas como sempre, aqui vão algumas dicas que me foram indispensáveis. Estou rodando Xubuntu 12.10 64bits.

• ALSA: Se você acompanha o Cafe-TI sabe que sempre desinstalo o PulseAudio do Ubuntu ou Xubuntu pois causa problemas de performance, barulhos, cortadas e desalinhamento de áudio com vídeo, principalmente usando áudio onboard como faço (nunca tive uma placa de áudio decente para experimentar). O Steam parece usar o PulseAudio por padrão, mesmo que não instalado no seu Linux. Para força-lo a usar ALSA, basta adicionar SDL_AUDIODRIVER=alsa antes do steam em sua linha de comando. Eu acabei criando um script em bash que da um export SDL_AUDIODRIVER=alsa antes do comando steam.
• Joystick: O Team Fortress 2 não iniciou até que eu adicionasse -nojoy em seus parâmetros de inicialização (pelas propriedades do jogo no Steam).

Cada vez mais vejo o pessoal novo do Linux perguntando… existe um viewer 64 bits que funciona tudo? Como ativar a parte multimedia (áudio/vídeo/música) no Viewer de 32 bits, rodando num Linux 64 bits?

O problema é que os Linux mais comuns de 64 bits vem apenas com o tal de gstreamer em 64 bits, e não permitem instalar a contraparte de 32 bits sem bagunçar tudo e dar um nó na cabeça. Este gstreamer é o que permite tocar streamings de áudio e vídeo dentro do SL Viewer no Linux. Então a única solução viável, já que a Linden Labs não se da ao trabalho de compilar uma versão 64 bits de seu viewer, é usar um viewer 64 bits de terceiros.

Pois graças ao colaborador @ArminWeatherwax, temos uma opção muito boa, o Teapot. Parece tudo funcionar muito bem e com performance superior a qualquer outro viewer. O Imprudence ficou congelado em sua última versão 1.4 beta 2, sem Mesh e outras coisas novas, deixando esperanças no desenvolvimento de seu sucessor o Kokua Viewer, primeira versão alpha, que deixa um pouco a desejar em sua performance e bugs. Alguém tomou providências e lançou o Teapot para contribuir. Hoje também fui avisado de uma nova opção, o Singularity, que ainda vou testar… e resolvi compartilhar.

Links dos viewers abaixo. Aceito comentários complementando ou corrigindo os meus em cada viewer.

Links e Refs

Imprudence – No Mesh, no Flash media?

Kokua – Mesh, slow, bugs.

Teapot – Mesh, Fast, Stable.

Singularity – Mesh, testing… não consegui rodar. Quebra logo após o login pra mim. No site diz que próxima versão vão compilar em outro Linux fora do Fedora 16 para melhorar a compatibilidade.

in another world…

• PDroid Patch Remove - re-flash your ROM, or copy the original 3 files.

NoMoarPowah! Galaxy Tab stockblue theme based on ironheart’s theme.

• CwM install package

Kernels

• Use boot.img inside the ROM ZIPs if you want to try other CM9 MTD builds, like the CyanogenMod official and AOKP, which often don’t provide latin (P1000N/L) kernels.
• Flash with heimdall like this:
  heimdall flash –kernel boot.img –recovery boot.img
• Or just replace boot.img inside the ROM ZIP with your desired kernel.

ATENTION: I assume you are following the CM9 conversations in the XDA threads. Make sure you have the required flashing background. In sum, if not already in CM9:

• Must be on Gingerbread.
• Must be on ext4.
• Must have CwM Recovery.

The Overcome guide is a good start before you get to CM9.

Easy restock from Gingerbread, in case you get any strange simptoms.

• Flash full stock Gingerbread (with repartition).
• Flash Kernel with CwM. Doesn’t have to be Overcome, could be any CF-root kernel for your model. You can use the same one in the CM9 ZIP that you will flash.
• Boot directly into CwM Recovery, holding VolUp. No need to convert to ext4, since MTD will converto to yaffs2 anyways.
• Flash CM9 ROM and GApps!

Troubleshooting

• Coming from some variations of CM9 you might get assert error status 7. If you are up to editing the update script, try reading this post from HumberOS.
  Or try this in recovery, thanks ayysir.
  Else, do the full restock, Overcome dance.
• Mobile, Data, 3G problems? This ROM comes with the JPZ modem. You might need to flash your customary modem back. Just copy your modem.bin to /radio in the Tab.
• Laggy? Slow? Wipe Cache and Dalvik cache. Also try using the following configs in Performance Settings: Processor: Max CPU 1200MHz, Governor ONDEMANDX (go ahead and try others like SmartassV2, Smoothass and Lagfree). Memory Management: zRam 18%, Allow purgin assets and Kernel samepage merging (KSM). And reboot.
• @sbradymobile - For anybody with a SystemUI FC on the newest build go into Settings > System > Combined bar expanded settings > Expanded settings entries and uncheck/recheck at least one of the settings (I will push the fix this morning).  You can now change the order as well.
• Wifi sleeping: if your wifi is sleeping when it’s not supposed to, try setting Minimum CPU Speed to 200MHz.
