ois, como estava a querer comprar um portatil, fiquei bastante interessado no Acer Travelmate 290LMi, mas como tenho de utilizar linux para trabalhos da universidade fiquei de "pé atras" quando encontrei varios sites a mencionar falta de suporte da tecnologia centrino no linux (a intel nao fornece drivers).
como já tinha feito a encomenda do portatil, fiquei ainda mais apreensivo, e pedi na loja para fazer uma "pausa" no pedido.
agora encontrei este relato (o unico até ao momento) de alguem que tem o mesmo portatil e instalou linux:
Acer Travelmate 290LMi & Linux Debian (SID)
Specifications
-Pentium-M 1,3Ghz
-30Gb
-512Mb DDR
-DVD-RW (2x/1x DVD, 16x/10x CD)
-3 USB 2.0
-Integrated Intel Xtreme graphics (chipset 855GM, up to 64Mb shm)
-Built in Realtek 8139c
-Built in Intel Pro/Wireless LAN 2100
-IrDA (SMC)
-Modem Agere Systems AC'97
-Firewire
-1 Pcmcia
Installing linux
I've choosen Knoppix (version 3.2 dated 07/2003) because of its hardware detection and easy set up. Once it's been installed I've modified /etc/apt/sources.list and /etc/apt/apt.conf to match SID's and run "apt-get update && apt-get dist-upgrade":
-------
root@quinipt:/home/quini# cat /etc/apt/apt.conf
APT:
efault-Release "unstable";
APT::Cache-Limit 10000000;
Apt::Get:
urge;
root@quinipt:/home/quini# cat /etc/apt/sources.list
# Security updates
deb http://security.debian.org stable/updates main contrib non-free
# Unstable / SID
deb http://ftp.de.debian.org/debian unstable main contrib non-free
deb http://ftp.de.debian.org/debian-non-US unstable/non-US main contrib non-free

Here you can get the output from dmesg.
Touchpad
-Despite Knoppix sets X (v.4.3) to use any mouse (ps2, usb and serial), I had to change protocol from IMPS2 to PS2 in order for it to work. I sometimes use an usb mouse with no problems.
Wired LAN
-Works fine (8139too module).
Wireless LAN
-Doesn't work, no linux drivers.
Modem
-I've found a driver at Smart Link, but I haven't tryed it (no need).
ACPI
-I've downloaded vanilla kernel 2.4.22 from kernel.org and ac1 patch from linuxhq.com; here you can download my .config file .
It powers off, screen turns off after x minutes under X, cpu runs cooler and fan is always never on.
Centrino's speedstep
-AC1 patch adds centrino's advanced speedstep. This feature together with cpufreqd and cpudyn makes it work really cold: it runs always at 600mhz despite it needs more power. Cpudyn speeds the CPU up when needed and lows its speed when not.
Battery life
-Of course it depends on the use; my experience with this laptop, thanks to cpufreqd & cpudin, is about 4 hours battery life time.
DVD-RW
-290LMi models have a DVD-RW recorder. Mine's Toshiba SD-R6112, able to record DVD-R at 2x, DVD-RW at 1x, and 16x/10x CD-R/RW. I've been able to record all kind of media using Xcdroast & cdrecord.prodvd (non free, but free for a non commercial use).
PCMCIA
-It seems to be working fine out of the box.
USB 1.1
-Seems to work fine, as I usually use a Logitech usb mouse. Modules loaded are usb-uhci, input and mousedev.
Despite this I haven't yet been able of syncing my Palm m515 via usb. It seems not to create the apropiate link to /dev/usb/ttyUSB1 8-?
USB 2
-Untested. Insmoding ehci-hcd module shows:
-----
ehci_hcd 00:1d.7: Intel Corp. 82801DB USB2
ehci_hcd 00:1d.7: irq 10, pci mem e0a05000
usb.c: new USB bus registered, assigned bus number 1
ehci_hcd 00:1d.7: enabled 64bit PCI DMA
PCI: 00:1d.7 PCI cache line size set incorrectly (0 bytes) by BIOS/FW.
PCI: 00:1d.7 PCI cache line size corrected to 128.
ehci_hcd 00:1d.7: USB 2.0 enabled, EHCI 1.00, driver 2003-Jun-19/2.4
usb.c: USB disconnect on device 00:1d.2-2 address 2
hub.c: USB hub found
hub.c: 6 ports detected

Firewire
-Untested. Insmoding ohci1394 module shows:
-----
ohci1394: $Rev: 1010 $ Ben Collins
ohci1394_0: OHCI-1394 1.0 (PCI): IRQ=[11] MMIO=[e0001800-e0001fff] Max Packet=[2048]
ieee1394: Host added: ID:BUS[0-00:1023] GUID[00023f3744005b60]
-----
IrDA
-It seems to have a supported chip by SMC, but I haven't been able to make it sync with my Palm m515 8-(
Insmoding smc-ircc shows:
-----
found SMC SuperIO Chip (devid=0x5a rev=00 base=0x002e): LPC47N227
SMC IrDA Controller found
IrCC version 2.0, firport 0x230, sirport 0x3f8 dma=3, irq=4
IrDA: Registered device irda0
-----
Extra buttons
-This laptop has got 2 extra buttons, called P1 and P2. You can give them any function using acme.
Sound
-The intel integrated sound card works after setting it through /etc/int.d/alsa-autoconfig
3D (DRI)
-Works fine (tryed tuxracer at 1024x768
)
Este é o relato de alguem que percebe bastante de linux. e mesmo assim, tem de utilizar "truques" para poder utilizar o portatil razoavelmente bem (nao há suporte nativo de ACPI, nao há UDMA, etc)
a minha duvida reside no seguinte:
-será que EU conseguirei instalar o linux de maneira que funcione? já ouvi alguns relatos de pessoal que nao conseguia
-será que o portatil vai funcionar de forma razoavel em linux? terei motivos de preocupação?
-será que no futuro relativamente proximo terei suporte oficial da intel ao linux? (já ouvi dizer que sim, e que não)
o que é que voces fariam? optavam na mesma por este portatil (com os possiveis problemas actuais em linux), ou compravam um "tradicional", que desse garantias de funcionar bem, mas com muito menor autonomia, e sem algumas das caracteristicas que tornam os centrino um pouco 'especiais'?
estou mesmo stressado com isto

mas quando tu encontras um determinado problema sobre algo que nao conheces muito, é complicado investigares, especialmente se a informaçao na net for escassa.
