Ahoj, přešel jsem z win na Linux. O Linuxu se říká že je to mnohem stabilnější systém. Velmi často mi moje Ubuntu zamrzne. Třeba když pracuju v Opeře. Jak z toho ven bez restartu?
Kombinace ctrl+alt+f2 také nefunguje, myš zmizí...
Je jiná možnost než restart na tvrdo? Díky, D.

Takové potíže jsou obvykle způsobeny hardwarovým problémem. Doporučuji se podívat do adresáře /var/log a přečíst si v logovacích souborech, jestli to něco nezahlásilo při tom pádu (nejnovější hlášky jsou vždy dole). Zkus si taky nainstalovat balíček memtest a v menu před startem systému tento program spustit. Nechej ho běžet alespoň půl hodiny, testuje velmi důkladně paměť a do spodní poloviny obrazovky vypisuje chyby. Pokud se tam něco objeví, tak je problém obvykle v pamětech nebo základní desce.

Ctrl-Alt-Backspaceshodí pouze grafiku
takové chování systému není normální, a tak bych pátral po příčině
-
Ctrl+alt+backspace mám povolené pro restart gnome, ale přesto to nejde, když počítač vytuhne. Takže pokud nefunguje
ctrl+alt+f2 nebo ctrl+alt+backspace tak je už jenom jediná možnost - restart na tvrdo?
-
Pokud se nejde přepnout do textové konzole ani shodit grafiku, tak asi jiná možnost není (leda se přihlásit z jiného stroje do konzole? ale to asi taky nepůjde).
Podívejte se na ty logy, tohle není normální. Příp. zkuste nainstalovat ještě jiný systém (linux nebo Windows) či aspoň spustit z Live CD a pozorujte, zda to dělá taky.

je to iba taka rada na slepo, ale stoji za vyskusanie
skuste vypnut efekty v compize, mal som podobny problem kedy, mi kazde "popularne" distro mrzlo, a po vypnuti funguje
-
Nebo rovnou vypnout Compiz a prepnout na Metacity, nebo jak se to. A pokud to neni Compizem ani hardwarem, tak zkusit jine distro. Ubuntu neni vzdy zrovna prikladem stability. Doporucil bych radsi Debian testing.

Jeste je tu http://wiki.ubuntu.cz/SysRq

no pro restart xek delej spis pravy alt + (sysrq [klavesa tam kde je print screen]) + klavesa k
samozrejme je i kombinace pro umountnuti vsech disku a klavesa pro teply restart pc.
<Alt><SysRq>
(Non-essential.) This is a group of key combinations implemented at the Linux kernel level (a low level). It means, chances are these key combinations will work most of the time. The combinations are meant for debugging purposes and in an emergency (mostly developers); you should try other, safer solutions first. The key <SysRq> is also knows on PC as <PrintScreen>. The combinations can be enabled/disabled by setting the relevant kernel variable to "1" or "0", e.g. : echo "1" > /proc/sys/kernel/sysrq
<Alt><SysRq><k> Kill all processes (including X) which are running on the currently active virtual console. This key combination is know as "secure access key" (SAK).
<Alt><SysRq><e> Send the TERM signal to all running processes except init, asking them to exit.
<Alt><SysRq> Send the KILL signal to all running processes except init. This may be more successful in killing runaway processes than the previous key combination, but it may cause some of them to exit abnormally.
<Alt><SysRq><l> Send the KILL signal to all processes, including init. The system will not be functional.
<Alt><SysRq> Run an emergency sync (cache write) on all mounted filesystems. This can prevent data loss.
<Alt><SysRq> Remount all mounted filesystems as read-only. This has the same effect as the sync combination above, but with one important benefit: if the operation is successful, fsck won't have to check all filesystems after a computer hardware reset.
<Alt><SysRq><r> Turn off keyboard raw mode. This can be useful when your X session hangs. After issueing this command you may be able to use <Ctrl><Alt><Del>.
<Alt><SysRq> Reboot immediately without syncing or unmounting your disks. Your will likely end up with filesystem errors.
<Alt><SysRq><o> Shut the system off (if configured and supported).
<Alt><SysRq><p> Dump the current registers and flags to your console.
<Alt><SysRq><t> Dump a list of current tasks and their information to your console.
<Alt><SysRq><m> Dump memory info to your console.
<Alt>SysRq><digit> The digit is '0' to '9'. Set the console log level, controlling which kernel messages will be printed to your console. For example, '0' will cause only emergency messages like PANICs or OOPSes displayed on your console.
<Alt><SysRq><h> Display help. Also, any other unsupported <Alt><SysRq><key> combination will display the same help.

Nepodařilo se vyřešit,mě pomohlo instalovat jinou linuxovou distribuci,konkrétně CentOS.
Už jsem používal Mandrivu,pak Ubuntu,ale CentoOS je podle mě z nich jasně nejlepší.Skvělá
stabilita systému,už nemám problémy jako v Ubuntu.Přitom s verzí Ubuntu 8.04 jsem žádné
potíže neměl,ale 10.10 byla tragédie.
-
Podobne problemy mam aj ja v 10.04. Mrzne v nahodnych intervaloch, v zatuhnutom stave zostane par sekund a potom znovu chvilu funguje. Jednotlive incidenty sa objavuju nahodne, no vo vacsej miere ked mam zapnute torrenty. Niekedy mrznu len sietove spojenia zvonku, niekedy mrzne cely system (prestane sa refreshovat conky, na chvilu sekne video). V logoch nieje nic. Canonical by mal radikalne pribrzdit inovacie, lebo sam seba zlikviduje.
-
Furt to mrzne? A to se pritom oteplilo. Doporucuji jine distro, treba Debian. On Murdock je z Nemec a tam prece jen mrzne vic, nez v Canonicalu a tak to na to maji otestovane.
-
A do kterého logu konkrétně bych se měl podívat? ve /var/log je logů spoustu. Každopádně se mi taky stává že když zaklapnu víko notebooku (notebook se ale neuspí - je nastavený šetřič) a za hodinu třeba přijdu a chci pracovat tak mi gnome (lišty, obsahy oken, myš atd.. ) tak divně problikává.. a klávesnice se seká při psaní.. zkusím resetnout gnome bez resetu, jestli to pomůže.. uvidím. Každopádně čím by to mohlo být? :o)
-
Zase mi to vytuhlo. Tak sem se zkusil podívat do /var/log/syslog a systém vytuhnul v 09:47 - nešla ani myš, ani klávesnice. Zkusil jsem alt+sysrq+R (uvolnění klávesnice) a poté ctrl+alt+f2 .. nic... ale podle logu sysrq fungovalo. Nechápu to. Zde přikládám log, ze kterého moc jako laik nevyčtu. Doufám že mi někdo dá nějaký tip. Díky

Mě zamrzá Ubuntu téměř kdykoli se mu zachce. Zvláštní je vždy se vypne numlock a začne blikat indikátor capslocku. (Mám ntb) Nepomáhá snad nic kromě tvrdého restartu... Co to může způsobovat?
V logu se moc nevyznám, ale dnes mi os zase spadlo a jediné co je v logu je toto -

Vidim to na kernel nebo na aplikaci, ktera ho sunda. Zkus je postupne povypinat.
Chybu ze strany HW otestuj kdyztak pres LiveCD.

Co takto update-y. Dnes rano malo Ubuntu 10.10 udpate dbus-u
este by mozno pomohol vypis z lspci -vv

Systém je stále updejtován, na kernelu nezáleží (každý mrzne) a s hardwarem nic není (memtest - ok). Psal jsem na off. fóru, bylo my doporučeno SysRq, ale to také nepomáhá...

Me se to taky stavalo na notebooku Acer, ubuntu zacinajici pismenem L a vyssi zamrza, Hardy Heron a Karmic Koala je OK. Mozna je to tim, ze mam starsi notebook (2006) a nove Ubuntu uz neni kompatibilni.
